Training institutions are becoming more and more difficult to do, but why do some institutions do so well? What's the point?
As an institution, it is best to avoid behind closed doors. It is suggested to go out and have a look, observe other institutions and listen to lectures. For example, the courses of some well-known institutions, such as Xue Jun, Jinzhi, Langpei and Tengyue, are very limited to sitting in the office. Of course, we should do the same in class, but we should think more and be innovative.
