Ma Zhongying
British telegrams from British India in 1937 said that Tungans (Hui people, a.k.a. Chinese speaking Muslims) like Ma Zhongying and Ma Hushan had reached an agreement with the Soviets whom they had fought before; as the Japanese had begun full scale warfare with China, the Tungans, led by Ma Zhongying and Ma Hushan would help Chinese forces battle Japan. The Soviets would release Ma Zhongying, and he and Ma Hushan would return to Gansu. Sven Hedin wrote that Ma Hushan would "certainly obey the summons" to join the Chinese side against Japan in the war.
