Han Yu’s famous saying encourages us to ask more questions:

People are not born with knowledge. How can we be free from confusion? If you are confused and do not follow the teacher, it is confusion, and you will never be able to understand it.

This is a famous sentence in Han Yu's "The Master".

The meaning of this sentence is: People are not born knowing the truth, so who can be without doubts? If you have doubts and don't follow the teacher to learn, those that become difficult questions will not be understood in the end.

This is to encourage us to ask bold questions when we encounter problems that we do not understand. We cannot pretend to understand, otherwise, doubts will accumulate.
