Muslim Conflict in Gansu was when a coalition of Muslim Generals broke out in revolt against the Guominjun in 1927. Prominent among the rebels was Ma Tingxiang, the son of the General Ma Anliang, who received aid in the form of arms from Zhang Zuolin in Manchuria.

Famine, natural disaster, and use of their land for planting opium precipitated the rebellion of the people of Gansu under Guominjun rule.

Two Muslim Hui Generals, Ma Tingxiang and Ma Zhongying raised the flag of revolt, and attacked Guominjun forces throughout Gansu, participating in sieges of Hezhou.

The fighting was often brutal. The revolt degenerated from an anti Guominjun movement into general ethnic and religious conflict with Muslims, with mass atrocities on both sides.

Throughout the revolt, some Muslim Generals like Ma Fuxiang did not join in the revolt, remaining officially as a part of the Guominjun, and appealing for peace. At the end, Ma Fuxiang and his son Ma Hongkui defected to the Kuomintang without doing any fighting.

Some Muslim Generals like Ma Lin remained on the Guominjun's side and fought the rebels.

A revolt led by Ma Tingxiang (Ma T'ing-hsiang) (馬廷勷) (a son of Ma Anliang) in the spring of 1928 broke out among the Hui people in Gansu province against the Guominjun of Feng Yuxiang. The Fengtian clique under Zhang Zuolin sent weapons shipments to Ma to aid him in his revolt.

Linxia (Hezhou) was often wracked by these frequent rebellions. The entire southern suburbs of the city (ba fang) "eight blocks" was ruined in 1928 by savage fighting between the Muslims and Guominjun forces.

Ma Lin defeated Ma Ting-hsiang (Ma Tingxiang).

Ma Tingxiang was attacked by the Muslim General Ma Hongbin who was serving in Feng's administration in Ningxia.
