孟卯
A year after the Ming–Mong Mao Intervention of 1398, the tusi Si Lunfa died and a new generation of elites rose to power in Mong Mao. His son Si Xingfa, together with Dao Hun and Dao Cuan, conducted short lived raids on Ming territory before military retaliation by the Yunnan guard put a stop to that. The territory of Mong Mao was partitioned into five new administrative divisions each with their own tusi. Thereafter Si Xingfa paid regular annual tribute to the Ming until he was removed from office in 1413 for failing to observe proper tribute ceremonies, and offended an imperial envoy. His brother Si Renfa succeeded him.
