As for why the way of university lies in Mingde, it has been explained in the book "University", that is, from the emperor to the ordinary people, self-cultivation should be the foundation. It is impossible to corrupt people's roots, but the final details can be adjusted. Just as I am good to others, others are slowly good to me; I am slow to others, but others are good to me, which has never happened before. This is called knowing the root and the bottom, and it is the highest state of cognition.

PS: Today, it is of fundamental and positive significance to advocate the virtue of university. The simple truth is that a person with low morality is more terrible to have knowledge than to have no knowledge, and it is more harmful to society.
