As we all know, Zhonggong and Tuhua are two famous civil servant training institutions in China. In fact, the two have their own advantages. If it is necessary to make a clear distinction, I still think painting is good, because it is a bit difficult for Zhonggong to agree to refund the fee. Take reference books as an example. Painting emphasizes routine and the speed of solving problems in a short time. Everything starts from actual combat, which is very organized and formulaic. The General Formula of Application and Mathematics compiled by Tu Hua can be directly applied to the examination room, which opens a way for many math idiots like me to solve problems quickly. On the surface, Zhonggong emphasizes logical thinking and pays attention to cultivating thinking methods and habits. The explanation is also easy to understand and contains great wisdom, but from the inside, it feels empty, that is, it took a lot of effort to finish reading the book and finish the problem, and found that there was no gain at all, which was rather pit.
