In the spring of April, we met again. Friends who are locked at home, grab more food, care more about friends who are in difficulties around you, and try to make life better. Don’t be hungry. You can also learn more and watch more Looking at history, the world has not changed, and humans have not changed.

These platforms have a well-developed ecology. They are generally spread through WeChat groups, and they play private domain traffic. Many people, especially some elderly people, often take classes on them. Although there are live broadcasts of these courses, they can basically be regarded as recorded broadcasts.
