Why should Confucius' birthday be regarded as Teacher's Day in China?

Answer; Because Confucius is the originator of education, it is a traditional ceremony to pay homage to Confucius on his birthday. This is not only to commemorate this most sacred teacher, but also to reflect the social expression of respecting teachers and attaching importance to teaching. It is best to regard Confucius' birthday as Teacher's Day, which is well-founded and traditional. Today's Teacher's Day is scheduled for September 10, but it seems that respecting teachers and attaching importance to teaching is for the sake of respecting teachers and attaching importance to teaching, and it lacks due cultural connotation. Taking Confucius' birthday as Teacher's Day, connecting with traditional culture, solved the legitimacy problem of a public holiday.
