What do you mean, the weather changes without fear, people speak unkindly, and the laws of their ancestors are not observed!

Judging from the Biography of Wang Anshi, in the Northern Song Dynasty, Wang Anshi advocated political reform and put forward this famous theory of "three shortcomings". "Things don't change": the original intention is that there is no need to be afraid of disasters in nature. It is a response to people attacking the new law with all kinds of so-called "natural anomalies" at that time, and at the same time reveals a simple materialistic thought; "Ancestor deficiency law": if the laws and regulations formulated by predecessors do not meet the current needs or even hinder social progress, they must be revised or even abolished, and they cannot be blindly inherited and imitated; "insincere": don't worry about gossip. This is both the spiritual pillar of Wang Anshi's political reform and his ideological weapon. Since the Song Dynasty, people have often quoted this sentence to express a spirit of continuous innovation.
