Шэн Шицай
Ishaq Beg Munonov was a native of Ulugqat in western Xinjiang. Shortly after the Russian Revolution of 1917, he moved to the Soviet Union to study and became a follower of Marxism. After returning to China in 1922, he was imprisoned for espousing revolutionary beliefs and urging the Kyrgyz to rise up against Xinjiang governor Jin Shuren. He later served as a regiment and then a brigade commander in the army of Sheng Shicai who supplanted Jin Shuren as governor in 1933. Some sources say that Ishaq Beg was a spy sent by Soviet intelligence to Xinjiang to support Sheng Shicai.
