毌丘儉
Wei felt humiliated when Wu began infringing on its territory by doing construction works on the Dongxing dam. The Wei general Zhuge Dan proposed to the regent Sima Shi a plan to counter Wu, and Sima Shi accepted his idea. In December 252 or January 253, the Wei imperial court commissioned Wang Chang, Guanqiu Jian, Zhuge Dan and Hu Zun (胡遵) to attack Wu from three directions: Wang Chang would attack Jiangling; Guanqiu Jian would attack Wuchang (武昌; present-day Ezhou, Hubei); Zhuge Dan and Hu Zun would lead 70,000 troops to Dongxing to attack the two castles and damage the dam.
