Since Apple’s hardware products had their own conference, WWDC Conference (Apple Global Developers Conference) began to return to the essence and became a stage for Apple to show developers the latest systems and software. On this stage, the most eye-catching protagonists are OS X(OS Ten, which stands for 10) of Mac and iOS of iPhone. So what is the development process of OS X and iOS?

　　Mac OS X 10.0 Cheetah

　　Mac OS X is the tenth generation system of Mac OS, but it is actually completely separated from the previous MAC OS (Macintosh system), with completely different underlying architecture and more gorgeous visual effects. In the early stage of OS X, it was named after cats, and later changed to the names of California attractions.

　　On March 24th, 2001, Apple introduced OS X 10.0 Cheetah. Although its operating speed is slow and its functions are not complete, because it rewrote a completely different system, the system kernel has fewer bugs and excellent stability.

　　Mac OS X 10.1 Puma (jaguar)

　　On September 25th of the same year, the launch of Mac OS X 10.1 Puma enhanced the running efficiency of Cheetah, and introduced functions such as color management and DVD playback, which was the first default operating system of Mac in OS X version.

　　Mac OS X 10.2 Jaguar (Jaguar)

　　On August 24th, 2002, starting from Mac OS X 10.2 Jaguar, Apple officially announced that it would name OS X after cats. This update added as many as 150 functions, and the system interface became more dazzling.

　　Jaguar is the first version of OS X with official code name, and the OS X system has gained a lot of praise since then.

　　Mac OS X 10.3 Panther (panther)

　　Only two months after the last version, OS X has been updated again. Safari, a famous web browser, has replaced IE as the exclusive browser of Apple Mac OS X in this generation, and now it is also the default browser on all Apple devices.

　　Mac OS X 10.4 Tiger (tiger)

　　At the WWDC conference in 2005, Mac OS X 10.4 Tiger with more than 200 updates came. Spotlight search was added in this update, and the processing ability of the system in editing pictures and images was greatly improved.

　　Mac OS X 10.5 Leopard (leopard)

　　Since 2005, WWDC can see the update of Mac OS X every year. Mac OS X 10.5 Leopard is the first Apple operating system certified as standard UNIX, which has a better interface and can support both PowerPC and Intel-core Macintosh computers.

　　Mac OS X 10.6 Snow Leopard (snow leopard)

　　At the WWDC conference in 2008, Jobs officially released the Mac OS X 10.6 Snow Leopard. Now, the Chinese handwriting function and screen sharing function of the touchpad commonly used on the MacBook are added in this generation of systems.

　　Mac OS X 10.7 Lion (lion)

　　At the WWDC conference in 2011, Mac OS X, which has been used for many years, was sold in the form of online sale+download. This update is of great significance.

　　The full range of iLife software has been updated, and functions such as multi-touch and gesture operation have been introduced. The familiar Launchpad interface was also introduced in this version, and programs can be run in full screen. More importantly, a brand-new MacAppStore has been launched, and the AirDrop function that we commonly use now has been added.

　　From this generation of systems, we can see that iOS, which was born out of OS X, began to have a negative impact on OS X, and the two systems began to have more and more in common.

　　OS X 10.8 Mountain Lion (puma)

　　In 2012, OS X 10.8 Mountain Lion was officially released. Since this generation, Mac OS X has officially changed its name to OS X.

　　This update has strengthened iCloud cloud service, and the connection between Apple devices has become closer, even replacing iCloud, which has been used for many years, with a more powerful Message. In addition, the new system provides more comprehensive support for many popular Chinese functions and services.

　　OS X 10.9 Mavericks (American surfing resort)

　　OS X 10.9 released in 2013 did not follow the name of cats (perhaps because the name is running out, XD), but was named Mavericks, a surfing resort in California.

　　This update focuses on strengthening the function of multi-screen display. The content on each display screen can become an independent working desktop, and the full-screen application and program switching operations will not be affected, which greatly improves the work efficiency of users.

　　OS X 10.10 Yosemite (beautiful resort)

　　The latest OS X 10.10 Yosemite interface deeply integrates the flat design style, and uses a large number of ground glass special effects, making the overall look and feel more concise. The new notification center is more flexible, and users can handle notification information more efficiently. It also added global search, iCloud Drive cloud disk, Mail Drop and other functions to further enhance the user experience.

　　Of course, the most worth mentioning is the Handoff function. As long as the iPhone is within the Handoff recognition range, you can answer, make calls, reply to text messages, emails and other operations on the Mac, which is very convenient.

　　Looking back at the evolution of OS X, we can find that Apple has always been committed to providing users with an efficient and fast experience, and strives to make the connection between Apple devices closer. This is also the guiding ideology of the iOS system. Let’s review the development of the iOS system!

　　IPhone runs OS X.

　　At the beginning, Jobs said that he wanted to run OS X on the iPhone, so the iPhone was equipped with a large screen, multi-finger touch technology, support for gravity sensing, a virtual QWERTY keyboard and a Safari browser, all of which made the contemporary "smart phones" unattainable.

　　Of course, there are many immature places in the first generation of iOS, such as the inability to replace desktop wallpaper, the lack of App Store, and the lack of support for installing applications. All this is unimaginable now. However, Apple’s idea of building hardware with user experience as the core has not changed.

　　iPhone OS 2.0

　　In July 2008, iPhone OS 2.0 was officially released (yes, it was renamed! ), since this generation, Apple introduced the AppStore, where users can download and install apps directly, and they can easily buy paid software. As early as Nokia was still king and Android was not yet a climate, Apple was already building a very popular "ecosystem" in these two years, which created the gap between iOS and Android today.

　　iPhone OS 3.0

　　The evolution of iPhone OS 2.0 is huge, and of course the price is high. Apple used the whole generation of iPhone OS 3.0 to improve the functions of the iPhone. Today’s iPhone supports Spotlight search, MMS, video recording, cutting, enlarging, copying and pasting. Oh, by the way, the system running on iPod touch and iPad is also called iPhone OS.

　　iOS 4

　　Jobs found that iPhone, iPod touch and iPad all run iPhone OS, which may be inappropriate, so iPhone OS officially changed its name to the familiar iOS.

　　Multi-tasking is a highlight of iOS 4. In addition, FaceTime, folder creation and other functions have been added.

　　iOS 5

　　In iOS 5, Siri, who loves to tell cold jokes and is not fluent in Chinese, began to settle in every iPhone, and the addition of iMessage saved us a lot of SMS fees, as well as the iCloud service that caused several "pornographic photos" incidents. It also officially met with us.

　　Starting from iOS 5, you can finally get rid of your PC and upgrade your system by OTA.

　　iOS 6

　　At the WWDC conference in June 2012, iOS 6 was officially released. Apple abandoned Google Maps, an old buddy who had cooperated for many years, and replaced it with Apple Maps independently developed by Apple. However, when Apple Maps came out, there were many mistakes and omissions, and Cook also issued an apology statement for this.

　　This update makes Siri smarter and adds a Passbook function, so that users can easily manage their payment information.

　　iOS 7

　　When iOS developed to the sixth generation, it basically became perfect, and the style of quasi-materialization was deeply rooted in people’s hearts. At this time, iOS 7 holding high the flat banner came!

　　IOS 7 not only brings a brand-new flat design style, more dynamic color matching, but also adds a brand-new control center, which strengthens the camera function and makes the multi-task interface clear at a glance. Most importantly, the deep combination of TouchID and the system has opened the way for Apple to deploy mobile payment.

　　iOS 8

　　Many iPhone users say that iOS 8 is the worst iOS system in history, and the increased power consumption, poor system stability and poor fluency are all the places where iOS 8 has been criticized.

　　However, iOS 8 is also the most open iOS system at present. The opening of a large number of API interfaces gives developers more room to play, and you no longer have to jailbreak in order to follow the third-party input method. In addition, the linkage with Apple Watch, the addition of Apple Pay, Handoff and other functions have made iOS 8 even easier to use.

　　IOS 9 is the next generation of iOS 8, which will undoubtedly further optimize the stability of iOS and make new development in the expansion of functions. Anyway, let’s look forward to what surprises Apple will bring us at the upcoming WWDC!

I found a rule: doing housework can make me feel calm.

Whenever my thoughts are upset, I will sweep the dust from the floor, clean the sink, or wipe off the floating dust on the table, and store the clothes on the folding clothes rack … Waiting for the indoor window to be clear, all my irritability and anxiety will rest in peace for a while, and I will have a bright good mood again.

When I said these words, I was a little hesitant. After all, I don’t want to poeticize all trivial tasks such as washing rags, cleaning garbage and sucking dust, and whitewash the already difficult situation of many housewives who struggle in housework day after day.

I mean, doing housework itself often brings me some comfort. This is not my own opinion, and similar remarks can often be seen scattered on social media. Moreover, there are scientific reasons!

01

Comfort of housework: gaining pleasure in doing housework?

Tidying up your desk, watering plants or folding clothes are all chores that do not meet the standards of hedonism. However, I often find that I can seek pleasure and comfort in these small repetitive tasks.

If I’m waiting for an important call, or I’m stuck in the writer’s block because I have an urgent task, I often choose to rearrange my collection of records or clean up the files around the office. Sometimes this is the most relaxing moment for me all day.

I’m not alone. When we are under the pressure of the epidemic, according to the report, many people say that they are interested in cleaning up their homes again as a way to cope with the uncertain life. On the oil pipeline, videos of some people doing housework even have a large audience, and some of the most popular video clips have been watched by millions of people.

Psychologists believe that there are many potential mechanisms to explain the perfect pleasure of relaxing life, and these relaxing behaviors are likely to encourage you to live a better life.

02

The scientific truth of housework and recreation

On the surface, doing some simple housework for recreation may be good for your mood. It occupies our brains, so we will pay less attention to the things that worry us. For example, we may struggle with our own thoughts in our brains, but we also find that housework can fix us in the here and now. This mainly depends on where we focus.

In a study on the effects of washing dishes on mental health, researchers from Florida State University divided 51 participants into two groups. Half the people were asked to read the article, encouraging them to focus on the feelings generated by activities. "When washing dishes, you should be fully aware of the fact that you are washing dishes." The other half read the instructions on how to wash dishes, but no one explicitly encouraged them to focus on the feeling of washing dishes.

Afterwards, the researchers asked the participants to fill out a questionnaire about their experience. Those participants who had full sensory experience reported that their mood was significantly better. The specific content includes that their nervousness has decreased, and they even have a kind of "inspiration" for generate. Immersing themselves in simple activities for a while will refresh their minds.

03

Enhance the ability of perception control

Different from other distracting activities, such as playing computer games or watching soap operas, doing housework for recreation also has an obvious advantage, which is to increase our sense of control.

When we feel anxious, helplessness will aggravate the physiological stress response and increase the level of hormones such as cortisol. In the long run, helplessness will even damage the function of the immune system.

Ideally, we would deal directly with the disturbing situation itself. However, research shows that we can gain a sense of control from activities that bother us but have little impact.

Stacy Bedwell, a psychologist at the Institute of Psychiatry, Psychology and Neuroscience at King’s College London, said: "We will believe or feel that we have control, but it doesn’t have to be consistent with the actual control situation." She said. Being able to change our environment can create a beneficial sense of control, which can also explain why cleaning and tidying up our home makes people feel so healed.

Some studies on the elderly also prove this view. Professor Allen Langer of Harvard University and Professor Judith Rodin of Yale University conducted a classic study. The study was conducted in a nursing home and participants were divided into two groups. The first group of participants were allowed to change the room according to their own ideas. They can decorate their furniture at will and get a plant. They need to take care of themselves. At the same time, the second group of participants were told that the staff would take care of everything in the room, and they didn’t even have to water the plants. In the next 18 months, the residents in the former group who are in charge of their own rooms are in better health than the latter group.

For example, grouping objects by color can provide better exercise for the brain to control chaos. The former group of participants may have received more exercise than the latter group. Langer and Rodin believe that this kind of exercise is mainly psychological, and their sense of control over life is enhanced.

04

A tidy room, a focused heart.

The benefits don’t stop there. If your housework is mainly organized, you may find that a cleaner environment will bring you comfort.

As Ethan Cross, a psychologist at the University of Michigan, wrote in his book. If we see order in our living environment, our inner feelings will not be so chaotic. "It can make life more predictable."

Bedwell points out that this may have a significant impact on your ability to concentrate. "If you sit at the kitchen table and your laptop is surrounded by clutter, then your brain must constantly deal with a lot of visual stimuli, and at the same time you should try to concentrate on the task at hand. Eliminate visual confusion and you can concentrate more easily. "

Brain imaging research also supports this view. Generally speaking, when you increase the number of distracting objects in the scene, your brain activity will become more intense, and every object is competing for our attention. This may cause your brain to become tired, making it difficult to concentrate for a long time.

What’s important is that you don’t have to remove the clutter to prevent this from happening, you just need to rearrange it. Grouping objects, for example, by color, can reduce some nervous confusion and improve our attention.

Doing housework can reduce anxiety, relieve stress reaction, increase attention and release endorphins. No wonder many people immediately choose to do housework when faced with uncertainty.

Like all activities, the benefits of these activities will be influenced by your personal taste and psychology. For example, the effect of running and other sports can be adjusted by people’s mentality. Sorting, cleaning and sorting are no exception. If you hate doing housework and only reluctantly pick up the broom, it may be difficult to get the pleasure of doing housework for recreation.

On May 28th, employees of a shopping mall in Nanning, Guangxi said that they would buy out the blind road at the entrance of the shopping mall and block it with stone piers, which caused concern. On the 28th, a disabled man in Nanning, Guangxi, sent a video saying that the barrier-free passage in front of Chaoyang Square in Nanning Times was blocked by the isolation pier placed by the property company, and it has not been removed after many reflections. The shopping mall involved responded that the staff said that it was a mistake to buy the blind road and would criticize and educate it. The shopping mall did not buy the blind road. The community to which the mall belongs responded that there had been an accident when the stone pier was not placed. Considering the potential safety hazard, the stone pier was placed to prohibit vehicles from entering. (May 29, Beijing News)

The blind road is a road specially designed to help blind people walk. It is a barrier-free facility, but it is blocked by stone piers. The employees of the shopping mall involved even claimed that the blind road has been "bought out", which is incredible. However, management is not a "buy-out", and you can’t take the blind road for yourself and do whatever you want. The author believes that barrier-free access can not be invaded, and the safety hazard is not a "shield" for stone piers to block blind roads. Relevant staff and managers must correct their wrong thinking, not only take measures to eliminate safety hazards, but also ensure that barrier-free facilities such as blind roads are unimpeded according to law, so as to protect the legitimate rights and interests of disabled people.

The community staff introduced that after receiving the complaint from the disabled man, the staff had gone to the scene to investigate. According to the feedback from the property company, the building in Times Chaoyang Square is a commercial and residential building, and many residents walk and play badminton in the square. When there was no stone pier on the blind road before, bike-sharing and battery cars often occupied the passage, and cars came in to park, which was easy to conflict with residents’ activities, which was neither safe nor beautiful. A signboard was placed next to the stone pier. If disabled people need to pass, they can call the number on the signboard and pass with the help of the staff. In other words, stone piers are used to block the blind road in order to prevent vehicles from entering the square for parking and eliminate potential safety hazards. This kind of rhetoric seems to have some truth.

However, the stone piers are placed on the blind road, where can the visually impaired people see them, let alone call the notice board for help? They walk on the blind road blocked by the stone piers, and if they are not careful, they will bump into or trip over the stone piers, which is simply a "trip-over", but it will increase the potential safety hazard. In fact, blind roads, as barrier-free facilities, cannot be arbitrarily disposed of and changed for use. Article 28 of the Law on the Construction of Barrier-free Environment in People’s Republic of China (PRC) stipulates that no unit or individual may change the use of barrier-free facilities without authorization or illegally occupy or damage barrier-free facilities. If barrier-free facilities are temporarily occupied due to special circumstances, guardrails, warning signs or signal facilities shall be announced and set up, and necessary alternative measures shall be taken. When the temporary occupation expires, it shall be restored to its original state in time. It can be seen that placing stone piers on blind roads is an illegal act that is not allowed by law and should be corrected and rectified.

The blind road is the "eye" that guides the visually impaired to move forward. Of course, there is no stone pier in the "eye". On the one hand, the property companies involved and relevant managers should enhance their awareness of the rule of law, move away from the stone pier as soon as possible to restore the original state of the blind road, and make this barrier-free passage unimpeded all the way; On the other hand, we can strengthen the order management of squares and nearby roads in conjunction with urban management, traffic police and other departments, add some traffic signs, regulate the orderly parking of vehicles in specified positions, put an end to disorderly parking and blocking barrier-free passages such as blind roads, so as to eliminate all kinds of safety hazards, which can not only ensure the safety of the general public, but also make the travel safety of disabled people. In this way, the nonsense like "buying out" the blind road, and the absurd things that occupy and block the blind road will not happen again.

Some barrier-free facilities such as blind roads have been changed or illegally occupied, which has become a common phenomenon in many cities. City managers and relevant units should strengthen supervision and punishment from the perspective of caring for the disabled, not only to further promote the construction of barrier-free facilities, but also to manage, use and maintain them well, so as to create a good atmosphere for the whole society to care for the disabled and make their travel more convenient and safe.

Live delivery is not an independent delivery channel. After layer-by-layer analysis, we can find that there is actually a complete supply chain model behind live delivery. Looking at other industries, we will find that the supply chain plays an incomparable role in the industry.

“Oh my god！”

"Buy it! Buy it! Buy it! "

Li Jiaqi, who just graduated from university in 2015, is still a BA (shopping guide) of L ‘Oré al Nanchang. Perhaps he didn’t expect that Taobao’s Double Eleven live broadcast could bring more than 1 billion goods five years later.

At first, many people thought that the live broadcast with goods was just the TV shopping when I was a child and moved to the Internet, which completely underestimated the economy of live broadcast with goods. During the "Double Eleven" in 2019, live delivery became an important growth point.

According to the statistics of Kaidu Consulting, during the Double Eleven in 2019, 90% of brands started live broadcasting, and the number of broadcasting businesses increased by more than 200% year-on-year. According to the "2019 Taobao Live Ecological Development Trend Report" released by Taobao List and Taobao Live,In 2018, the Taobao live broadcast platform brought hundreds of billions of goods, with a year-on-year growth rate of nearly 400%.

In addition, according to data released by Alibaba, in FY 2019, 50% of Tmall merchants used real-time streaming media to interact with users, resulting in a total turnover of more than 100 billion yuan.At present, the live broadcast of goods is that the anchor and fans form community marketing, and then the fans’ needs are directly passed on to the manufacturers, which is essentially different from TV shopping..

Since 2019, more and more people have participated in the game of live delivery. A top anchor like Viya has her own factory and cooperates with more than 40 factories, some of which deliver an average of 20,000 orders for Viya every day, but this is only a part of all her clothing orders.

In the face of huge economic benefits, the live broadcast supply chain has also formed a new species of supply chain system. The live broadcast supply chain has as many as 10 modes, including brand collection mode, factory production mode and boutique combination mode.

In Hangzhou, Guangzhou and other coastal areas, as long as there is a large enough warehouse, part of it is used as a live exhibition room, and then the goods selection area, the exhibition area and even the warehouse are separated in turn, thus satisfying the three elements of "people, goods and fields" in retail.Such a "supply chain base" is being rapidly replicated in the anchor. Closer to the goods, closer to the anchor, that is closer to the needs of consumers.

Compared with the traditional supply chain model, online celebrity, as the demand (shopping guide) end, is directly connected with the production end of products, eliminating the carrier of retailers. The original clothing wholesale business was disrupted by these "supply chain bases" brought by the anchors.

Zhejiang is a traditional distribution center for small commodities and clothing wholesale. Traditional clothing processing has always been the depth of the supply chain, which means that one style produces thousands of pieces, and it is enough to produce several such explosions in a season. And an anchor like Viya, the factory makes 30,000 pairs of jeans a day, and they sell them out in one night. The change of consumers’ shopping style directly affects the response speed of supply chain, the delivery speed of logistics and the digestion cycle of inventory. If the new model is not sold out in one month, it may be unsalable.

Supported by huge traffic nodes and driven by live broadcast, network anchors integrate consumers, e-commerce platforms, suppliers, factories, brands and online celebrity institutions (MCN) together, forming a huge supply chain network system, which is mutually cooperative and fast iterative.

This is the value brought by the supply chain with live broadcast to e-commerce, but the live broadcast supply chain is only a new species of the traditional supply chain. Supply chain management means that the operation of the supply chain is optimized, and the supply chain is made from the beginning of procurement to the satisfaction of the end customers at the least cost.

In the traditional supply chain process, there is a carrier (retail company) to purchase goods (source) from the source of production in advance, put them in the warehouse, and deliver and reorder according to the needs of customers. If you can, you can imagine that the simplest supply chain is the canteen downstairs in the community.

However, if the products are enlarged, for example, there are 80,000 SKUs (product bar codes) and 2,000 stores, then this is not a simple matter, and an extremely complex and systematic supply chain management system is needed.Apple, which has no production line, can get 58.5% profit from every iPhone it sells.It is no exaggeration to say that supply chain management, like product research and development, is a value chain gold mine for enterprises.

At the shareholders’ meeting of Hailan House in April, 2019, Zhou Jianping, the chairman of the board, clashed with the shareholders attending the meeting. The fuse was that investors questioned the high inventory of Hailan House. By the end of 2018,The inventory of Hailan House is 9.47 billion yuan, equivalent to three times the annual profit, up 980 million yuan from the end of last year and up 11.55% year-on-year..

In fact, this situation is not unique to Hailan House. Statistics show that as of September 30, 2018, among the 85 A-share textile and garment enterprises, 81 had an inventory of over 100 million yuan and 20 had an inventory of over 1 billion yuan.The total inventory of 85 textile and garment enterprises is as high as 98.564 billion yuan, which is higher than their total net profit of 17.251 billion yuan, and the inventory of almost all enterprises is much higher than their net profit.. High inventory is like the sword of Damocles hanging high, which will fall at any time and put the enterprise to death.

It can be said that whoever solves the problem of high inventory and reduces the inventory of enterprises is creating huge profits for enterprises.

Starbucks has more than 16,700 retail stores in 51 countries around the world, and about 5 million customers come to spend money every week.

In the early 1990s, Starbucks just went public, raised capital, and opened more than 1,000 stores in the United States in just 5-6 years. At the same time, the whole planning and supply system is still manual, and stores and buyers communicate with each other by calling from a distance through voice messages.

From the sales of one hundred million dollars to 700 million dollars, on the one hand, stores and businesses are developing rapidly, and on the other hand, manual and traditional communication methods are used. It is really common for stores to lack beans.

In this extraordinary period, Starbucks really survived with the unusual passion of its employees. Once the beans in any store were in a hurry, the manager of the nearby store grabbed a bag of bean human flesh and drove it over.

Tim Duffy, then head of Starbucks’ supply chain system, said:

"When you have more than 2,000 stores, we can’t send beans back and forth with 2,000 human flesh express."

Therefore, since 1995, Starbucks decided to upgrade the whole supply chain system, involving the end-to-end planning of the whole supply chain information system, from planning and forecasting to capacity management, production control, order execution, warehouse and distribution system, database management and transportation management.

Finally, Starbucks established a global coordinated supply chain. Starbucks has to go through 24 hands from coffee beans from all continents to a cup of ground coffee. Starbucks has implemented a complete evaluation system and database for suppliers, which can accurately evaluate the performance of each supplier and use the demand forecasting system to predict the replenishment of coffee in stores.

A strong supply chain supports the expansion of Starbucks. In 1999, Starbucks opened its first store in Beijing International Trade Center. By 2019, Starbucks had opened 4,100 stores in 168 cities.

It can be said that without strong supply chain support, there would be no Starbucks today..

On April 12, 2018, Liu Qiangdong said, "JD.COM is not an e-commerce company. We are a company that uses technology to build supply chain services, and we use technology to provide supply chain services for our brands! This is why we have spent more than ten years investing in building a logistics system. "

In 2017, the scale of online retail in the United States was less than $500 billion, while that in China exceeded $1.1 trillion. The largest retail company in the United States is not Amazon, but Wal-Mart, and even by 2017, the proportion of online retail will be about 8%. China, on the other hand, is a different story. The largest retailer is JD.COM, and the proportion of online retailing exceeds 16%, almost double that of the United States.

Wal-Mart is known as a supermarket for the poor, because it has established a global supply chain and logistics system, and goods can go directly from factories to stores, and then directly to final consumers. However, the goods bought by domestic consumers are constantly spread to the terminal stores by the brand through the first-class agents, and the price increase and logistics cost of intermediate transfer are finally reflected in the commodity price, and the user pays the bill.

In addition to its own self-operated e-commerce business, JD.COM has quickly transformed itself into the retail infrastructure of China through its supply chain and logistics advantages built over the past ten years. So now supermarkets, restaurants and pharmacies in any city in China can be delivered to consumers through Jingdong Logistics.

Today, with big data and cloud computing, the combination of data and supply chain will make JD.COM a smart supply chain.

Smart supply chain makes the comprehensive expense ratio of self-operated retail in JD.COM less than 10%. What is this concept?At present, there are only a few two or three companies in the world that can achieve a comprehensive expense ratio of 10%. One of them is Costco of the United States, and its expense ratio is less than 10%.It can achieve a good profit with a gross profit margin of 11-12%. And most of our retailers in China and all over the world need more than 20% to make a profit, that is, the cost is about 15% to 20%.

What is the measure of our supply chain efficiency? Today, JD.COM manages more than 500 logistics centers in China alone, and the number of our products in the warehouse is close to 5 million, while our traditional retailers generally manage 150,000 SKUs. The management difficulty of 5 million SKUs is not 30 times that of 150,000 SKUs, but may be 300 times. It is not a linear increase, but an increase in geometric index. It can be said that Liu Qiangdong is right, and JD.COM is a technology supply chain company.

The cost of socialized supply chain in our country accounts for about 18% of GDP.This is the figure in 2016, but Europe and the United States are only about 7% to 8%, and Japan can achieve 5% to 6%. Our country has a huge manufacturing industry and a large number of brand owners. Everyone has worked hard to do business, and the quality of goods is good. The gross profit margin looks high, but the result is that they don’t make money, and they are all wasted and lost by inefficient supply chains.

The GDP growth of China in 2019 is 6.1%. It is foreseeable that this incremental curve will become smoother and smoother, and it will be difficult for enterprises to make money. To survive in the fierce competition, it is the product and operating costs.

Whoever does a good job in the supply chain is saving costs for enterprises, saving costs for enterprises and increasing profits for enterprises.

And this is the value brought by the supply chain.

　　Emotional kidnapping, service congestion, scheming and indulging … … In the daily scene of compulsory attention to WeChat official account after scanning the QR code, there is a logic that "you can’t XX without paying attention".

　　Pink-up has formed an industrial chain. On a variety of pink-up platforms, some weighing scale fans only need 7 cents each, and 3,000 pieces will be sold, with large quantities and discounts.

　　Compulsory attention to WeChat official account to earn traffic is only the first step, and other profitable behaviors such as taking personal information and accurately pushing advertisements will follow.

　　"Are you there? Vote for me?" Click on the link sent by relatives and friends, but I want to enter the voting channel only to find that I should pay attention to WeChat official account first; When I came to the door of the pharmacy, a small line appeared on the weighing scale, which was intended to help customers understand the basic health conditions such as height and weight: "Scan the QR code and you can use it"; I plan to drive away from the garage after shopping, but I don’t care that WeChat official account can’t continue to pay the fee … … In the scanning code again and again in daily life scenes, the list of "subscription numbers" of mobile phones becomes longer and longer.

　　Pay, add friends and get information … … With the rapid development of Internet and mobile payment, the operation of "scanning QR code" is becoming more and more popular, which brings a lot of convenience to people. However, at the moment of chasing users’ attention, it is not uncommon to force attention to WeChat official account after scanning the QR code. Stranger still, the WeChat official account may have nothing to do with the user’s ongoing activities.

　　Why can’t we "bypass" WeChat official account? The reporter’s investigation found that there is a hidden gold chain behind it.

　　Hit Xu Juntu/this magazine

　　Do everything possible just to attract attention

　　Use WIFI in public places, and use coupons for hotel bills … … There is a logic that "you can’t do XX without paying attention" in many scenes of compulsory attention to WeChat official account. The reporter combed and found that the reasons for pushing people to submit can be subdivided into three categories:

　　Emotional "kidnapping" type WeChat official account used the interpersonal network of the direct participants to "escort" with feelings, and distributed the task of paying attention to WeChat official account as an adjunct to voting and helping others.

　　White-collar Ling Lu inadvertently cleaned up WeChat and found that less than half of the "subscription numbers" were what he really wanted to pay attention to. "The most common situation is voting. You must first pay attention to WeChat official account, the sponsor of the voting." Ling Lu said that due to family ties and friendship, I can’t help but vote. Sometimes I forget to cancel my attention after voting, and I have saved so much unconsciously.

　　Service "jam" type. The public company cooperates with the merchants to take "paying attention to the public company" as a compulsory channel for users to complete services and attract traffic.

　　When Cheng Xiaoqi, a citizen of Nanchang, Jiangxi, recently parked in the underground garage of a large shopping mall, he was asked to pay attention to a WeChat official account named "Stop on time" with WeChat. When asked whether direct payment could be made without paying attention to WeChat official account, the staff said no. Cheng Xiaoqi questioned: "What can be solved by scanning a receipt code? Why do I have to pay attention to WeChat official account?"

　　Click "Stop on time", and the main body of this account is Jiangxi Yixing Intelligent Parking Management Co., Ltd. The reporter called the company’s customer service, and the other party said that the cooperation between WeChat official account and the parking lot would require the parking lot to guide users to pay fees through the platform, which was a business model, and he was concerned that WeChat official account "would not bring any losses to car owners". When the reporter further confirmed that "I don’t care if I can’t pay for leaving", the customer service first said that there is another QR code that can pay directly. After the reporter said that he didn’t see the QR code in the relevant parking lot, the customer service also called "it depends on the parking lot".

　　The "inducement" type. The public party, that is, the service provider, defaults to the platform as the "necessary carrier" for using services and offers to guide attention, which is more concealed.

　　Nowadays, when you go to a restaurant to spend money, some restaurants no longer provide paper menus. The waiter will remind customers to order through the QR code posted on the corner of the table. And many ordering QR codes ambush a "careful machine": only when you pay attention to the WeChat WeChat official account of the store can you order food; Linking attention to WeChat official account with preferential activities has become one of the means for most "no paper menu" hotels to retain guests.

　　"weighing scale fans" are 70 cents each.

　　In the Internet age, fans mean value. It is WeChat official account’s desire to "suck gold" after rising in powder, which triggered a series of operations to pay compulsory attention to WeChat official account.

　　Mr. Zhang is the head of an operation in WeChat official account, where a single tweet has been read more than 100,000 times. He revealed to reporters that the current cost of acquiring a fan through official channels is around 5 yuan to 10 yuan. Because of the high cost of obtaining customers, only WeChat official account, a capital-rich head, can afford it, and most WeChat official account can only choose unofficial channels to raise money at the initial stage.

　　Search for "WeChat official account Pink" in Baidu, and a variety of pink platforms will come into view. Industry insiders told reporters that at present, Fanfen has formed an industrial chain. The accuracy of fans, the richness of equipment channels and the professionalism of customized solutions have become the main means for platforms to compete for customers’ competitiveness, and compulsory attention has become the main means for platform offline customers.

　　The reporter investigated a powder-increasing platform that mainly helps customers realize their demand for powder-increasing through offline equipment, and found that there are many offline scenes promoted on its corporate homepage, including weighing scale, doll machine, shared charging treasure, vending machine, hospital equipment powder-increasing, karaoke powder-increasing, WIFI powder-increasing, etc. There are also differences in retention rate, age group and price among different channels.

　　For example, if the hospital equipment is powdered, users can pay attention to WeChat official account to receive environmental protection bags or medical records for free by scanning the code in the hospital. The retention rate of fans in this scene is 60% to 80% of that day, and the age group is 18 to 45 years old; The doll machine adds powder by inducing users to scan the code to pay attention to WeChat official account’s voucher collection. The retention rate of fans is 60% to 80%, and the age group is 18 to 35 years old.

　　"This company is well-known in the industry and has offline equipment all over the country. Because the equipment is laid directly offline, the customer’s cost of obtaining customers is relatively low. The cheapest weighing scale fans only need 7 cents each, and 3,000 are sold, with a large quantity and a discount. " Sales staff said that many so-called powder-increasing platforms on the Internet actually don’t have the ability to get customers offline, and most of them cooperate with first-hand customer-obtaining platforms like them to earn the middle price difference by being a "profiteer".

　　Another powder-raising platform has only three ways of powder-raising: paper towel machine, weighing scale and WIFI. The price of powder-raising package in weighing scale is: 1,000 fans 900 yuan, 4,000 yuan for 5,000 fans and 7,000 yuan for 10,000 fans. The prominent position of its homepage is also straightforward, indicating that the number of customers served has exceeded 25,000, with a cumulative increase of 90 million, and the amount of powder increased by more than 120,000 that day.

　　Seemingly voluntary, but actually compulsory.

　　Is there any infringement in WeChat official account’s behavior when he is forced to pay attention to "no consultation"? According to the experts interviewed, under the premise of consumption, it is a kind of "voluntary in form and compulsory in essence" for merchants to force consumers to pay attention to WeChat official account.

　　"You must scan the code to pay attention to WeChat official account to order food, which is suspected of infringing on consumers’ right to choose independently." Gu Zhiming, Secretary-General of Jiangxi Consumer Protection Committee, said that Article 26 of the Consumer Protection Law stipulates that operators shall not exclude or restrict consumers’ rights, reduce or exempt operators’ responsibilities, increase consumers’ responsibilities and other unfair and unreasonable provisions to consumers by means of format clauses, notices, statements and shop notices, and shall not use format clauses and technical means to force transactions. Format clauses, notices, statements, shop notices, etc. contain the contents listed in the preceding paragraph, and their contents are invalid.

　　What’s more, according to industry insiders, the ultimate goal of business promotion is to turn online traffic into offline revenue. It is only the first step to pay compulsory attention to WeChat official account to earn user traffic, and other profitable behaviors such as obtaining personal information and accurately pushing advertisements will follow.

　　Zeng Yue, a lawyer of Jiangxi Qiuzheng Ward Law Firm, said that when WeChat users pay attention to WeChat official account, they will often receive a prompt that "WeChat official account has applied for your WeChat avatar, nickname, region and gender information". If they don’t click "allow", they will not be able to pay attention and get the services provided by WeChat official account. There is also the risk of revealing personal information for WeChat users, especially the elderly who are not very likely to use mobile phones to surf the Internet.

　　"The original intention of QR code is to make life more convenient, but it is mandatory to pay attention to what WeChat official account can consume ‘ Additional terms ’ To a certain extent, it also excludes the consumption rights of non-netizen groups. " Ruan Xinyi, a lawyer of Shanghai Jintiancheng (Nanchang) Law Firm, said that in the context of Internet consumption becoming a general trend, it is the only way to win the support of consumers to advocate businesses to simplify operating procedures while providing high-quality Internet products or services, to exercise their rights to the minimum extent and to protect the rights of network users to the maximum extent.
