Villages in China have enjoyed their development in a digital (数字) way in recent years. With the help of digital technology (技术), villagers are living an easier and happier life.
Farming in the past was not an easy job. Farmers worked hard all year round. At the same time, they usually found it difficult to solve problems like plant diseases and pest (害虫). Now, there have been big changes in farming. For example, in Dayi County, Sichuan Province, AI machines help local farmers know when and how to fertilize (施肥) and kill pests. In this way, they make farmers work more easily with less time and energy.
Thanks to the Internet, a new business called rural e-commerce (乡村电子商务) grows. Selling fresh fruit and vegetables to cities is faster. The business also helps villagers live a digital life. They can get many things done on different kinds of apps. They can also use drones to help with their farm work.
More visitors travel in beautiful villages because of digital technology. A good example is Huacheng Town, Guangdong Province. Visitors can know where to park their cars for free, when to book a ticket easily and what to buy online. They can also enjoy the view of nearly every part of the town by using VR.

501—8, 000 steps: Most students and workers will take between 501 and 8, 000 steps a day. These step counts are often in the middle of the leaderboard.
8, 001—30, 000 steps: Salespeople and P. E. teachers often take so many steps a day because they are always on the move.
More than 30, 000 steps: Mostly, these step counts can be on the top of the leaderboard. They are policemen, reporters, cleaners and so on. They are the people who help us live easy and comfortable lives.
As the number of people who use WeRun is growing, a person’s WeRun data can show his or her character and personal life.
