This section is devoted to the methods of education and learning, covering all aspects, from teaching according to the time, receiving from people, inspiring and inducing, to learning from each other. It can be said that it is very comprehensive to learn from each other's strengths. The problem of methods is very important because it is directly related to the success or failure of teaching and learning. In fact, it is not only education, but almost all practical activities have methodological problems. No matter how great and attractive the goal is, it is difficult to achieve it if the method is wrong. The idioms "get twice the result with half the effort" and "get twice the result with half the effort" all talk about methods, and also illustrate the importance of methods in practice.
