Jin Shuren
Nevertheless, the Xinjiang Governor Jin Shuren (1928–1933), sought to take advantage of the power vacuum left after the death of Shah Mahsut and decreed the abolition of the Kumul Khanate, preventing the new ruler, Shah Mahsut's son Nazir, from assuming control. At the same time, Jin Shuren arranged for Han Chinese migrants from Gansu to settle in the abolished Khanate. These events sparked the Kumul Rebellion in 1931, which was led by Hui warlord Ma Chung-ying in Gansu after his June 1931 meeting with Hoja Niyaz and Yulbars Khan. Ma Chung-ying agreed to add his troops to the campaign to topple Jin Shuren. Hoja Niyaz also received support from the Mongolian People's Republic: in autumn 1931 they provided him 600 sets of winter clothes, felt tents and 120 rifles (which were actually bartered for horses, one rifle was given for two horses).
