Shi Yousan

Shi Yousan (1891-December 12, 1940) was a KMT general who defected to, and subsequently betrayed, Feng Yuxiang, Chiang Kai-shek, Wang Jingwei, Zhang Xueliang, the CPC and Japan, in that order.

In 1928, his troops set fire to the Shaolin Monastery, burning it for over 40 days, destroying 90 percent of the buildings including many manuscripts of the temple library.

While leading the 39th Army Group, he planned to defect to the Japanese, but before he could do so he was kidnapped and killed by his sworn brother and subordinate Gao Shuxun, who later gained command of this unit.

For his many betrayals and defections he is known as the "Defector General" or as Shi Sanfan (, "Shi who turns coat three times").
