Yu Xiusong

In 1922, he supported the Constitutional Protection Movement of Sun Yat-sen. As a result of the First United Front in 1924, Yu was given a position in his home province by the Kuomintang.

In October 1925, Yu went to the Soviet Union to study at Moscow Sun Yat-sen University, where he became acquainted with Wang Ming.

At the instigation of Kang Sheng, Wang had Deng Fa arrest Yu on charges of Trotskyism sometime between December 10 and 27, 1937.

Yu's death marked the final break between Wang and Zhang Guotao.

In 1962, after the Sino-Soviet split, Yu was posthumously proclaimed a revolutionary martyr.
