Overall:
During the Wei Gong Emperor's reforms, he did not completely abandon the good practices of the feudal dynasties in the past to restore production and stabilize the people's lives. For example, Tianzi kisses five baht money to cultivate the land, persuades the peasants to command, opens warehouses in disaster years to alleviate poverty, and various types of relief, strikes and bans, and so on. One of the important measures is the promulgation of the equalization system and its related systems.
