Is it the traditional culture of China for teachers to teach students?

People who studied in ancient times must have teachers. Teachers can be relied on to impart truth, teach research and answer difficult questions. People are not born to understand reason, who can have no doubts? With doubts and not learning from teachers, those who become difficult problems will not understand in the end.

Born in front of me, he understood the truth earlier than me, so I will follow him and regard him as a teacher; Born behind me, if he knew the truth before me, I should follow him and regard him as a teacher.

The tradition of studying as a teacher, where to consider whether he is older than me or younger than me? Therefore, regardless of status and age, the place where truth exists is the place where teachers exist.
