Guo Degang once said: "Heaven does not grow nameless grass, and the earth does not support useless people."

This sentence has two meanings. One meaning is that we are born with talents. Useful, everyone comes to this world with different missions, and they will have their own place here. So don't give up on yourself.

On the other hand, it shows that people must have their own value to survive in society. Through continuous learning, one must be accepted by others, thereby realizing one's own growth significance in society.
