"。 " "The Doctrine of the Mean" says: "Therefore, a gentleman respects morality and asks about learning, making it broad and subtle, extremely bright and moderate, learning new things by reviewing old ones, and being sincere and respectful of ceremony". It means that a gentleman should respect morality and learn; It is necessary to enrich the broad, but also to exhaust the subtle; It is necessary to have brilliant ideals and moderate behavior; It is necessary to be familiar with old knowledge and constantly know new things; Be honest and kind, and learn manners. Although "respecting morality" refers to carrying forward one's innate goodness, it is idealistic from the theory of goodness; But "Taoist inquiry learning" also contains the elements of acquired learning and hard work. Here, the relationship between the formation of ideological and moral quality and the mastery of cultural knowledge is also preliminarily linked, and it is considered that these two ways are interdependent and complementary. There are some reasonable factors in this.
