Jo and his supporters then pushed forth a series of radical reforms as they established local self-government system called Hyang'yak to strengthen local autonomy and communal spirit among people. In this system, deference was placed according to senority of villagers rather than their social status. The Sarim faction also sought to reduce gap between the rich and poor with a land reform that would distribute land to farmers equally and limit amount of land and number of slaves that one could own. This measure also targeted Hungu faction's accumulation of land and wealth.
