Do you know why the ancients asked the scholar to add an acid word?
Because they concentrate on reading all day, they really ignore interpersonal relationships, and then not all scholars can become government officials and make a fortune. Some scholars think that they are incompetent and excellent, why can't they reach the realm of others? He will complain, and people who complain too much will naturally feel that he has been sour there, thus forming the name of a poor scholar.
