What were all the Mongolian ministries doing when the prince had an accident?

The battle of Jingnan began at 1399 and ended at 1402. During the short period from 1388 to 1402 in Mongolia, Khan appeared five times. 1388, Deere killed Timur of Tuogu Temple to usurp the throne, and then Cohen, Erbok, Kun Timur and Gui Lichi became "great Khan" one after another, but they died one after another soon, and most of them died in accidents. Inner-fighting Mongolian Khanting is constantly threatened by the increasingly powerful Walla Department in the West, and it is impossible to fish in troubled waters in the south.
