Tao Te Ching: A little will lead to gain, a lot will lead to confusion. Its knowledge will be too far, and its knowledge will be too little. It means that the more you know, the more confused you become, because the old knowledge is in conflict with the current society, which limits people's knowledge.

This is why a sage knows without doing, is famous without seeing, and is accomplished without doing.

It means that people should focus on gaining knowledge through current practice, rather than adhering to other people's words and ancient wisdom. After all, one's own knowledge comes from practice. Even if you memorize other people's knowledge and don't practice it, you won't know it. After all, understanding the profound meaning belongs to others and will eventually be slowly forgotten. Therefore, it is said that what you see on paper is ultimately shallow, but you definitely know that you have to do it in detail.

True knowledge comes from practice. Some people say that real knowledge is engraved in the heart and will never be destroyed. Why not say this sentence as "real knowledge is what is left after forgetting. They are what you get from practice. They are yours. Yours is Unique. Others may sound reasonable, but if you don’t put it into practice, if you treat it as a concept, it will be naturally eliminated by memory. This is learning without thinking, and thinking without learning is dangerous.
