Hukou incident

Hukou incident is an attempted coup d'état that took place on January 21, 1964 at Hukou, Hsinchu, Taiwan. During a staff meeting at the 1st Armor Division headquarter, General Chao Chih-hwa (趙志華), then deputy commander of the armored battle group, criticized General Chou Chih-jo (周至柔), then Chief of the General Staff, on charges of corruption, and encouraged fellow officers at the meeting to revolt. He was reported as saying "Our leader is being deceived by treacherous people, we must move our forces to Taipei to remove them." ("当今主上为小人所蒙蔽，我们要把部队开到台北勤王清君侧") He was promptly arrested by two political warfare officers, but the army nonetheless received erroneous information that the 1st Armor Division was on the move, and had deployed troops to intercept the "rebels forces" that did not exist.

Chao was court-martialed and sentenced to death, but the sentence was never carried out. His sentence was later reduced to life in prison after the death of Chiang Kai-shek, and Chao died in 1983. Chao's superior Chiang Wei-kuo, who was Chiang's adopted son, was also punished and never held any real authority in the military again.
