Thinking mathematics training is not necessarily limited to textbook knowledge points, but focuses on your understanding of the meaning of problems, finding problems, analyzing problems and solving problems. As for the olympiad, I don't need to say more. It is characterized by focusing on solving problems. To put it bluntly, it is a problem-solving competition and a good means of thinking training.

Some thinking mathematics institutions can be considered for introductory thinking training. For example, Peifei's thinking mathematics, 3-6 years old thinking training has advantages, and the key is to make children like it.
