Quan Cong (198–249),courtesy nameZihuang, was a military general of the state of Eastern Wu during the Three Kingdoms period. He was a son-in-law of Wu's founding emperor, Sun Quan, as he married Sun Quan's eldest daughter Sun Luban. He participated in the campaigns against the restless Shanyue tribes in the Wu territories and achieved success in pacifying them. In 228, he fought alongside the Wu general Lu Xun in the Battle of Shiting against Wu's rival state, Cao Wei, and scored a victory over the Wei general Cao Xiu.
In 241, he participated in a campaign against Wei, conquered Huainan commandery and destroyed the dam at Quebei (芍陂). Quan Cong's attack was well timed, as many of the soldiers of Yang province were being given leave at that time. At the opposing forces Sun Li led the defence at Quebei against Quan Cong, taking part personally in the fighting. He is said to have fought from morning to evening. Over half of Sun Li's soldiers were killed or wounded, and Sun Li himself received several wounds, as did his horse. However, he held his defense against Quan Cong, showing no concern for his personal safety until Wang Ling arrived with reinforcements and together with Sun Li counterattacked and successfully driving off Quan Cong from Huainan.
^ abcThe Sanguozhi mentioned that Quan Cong died in the 12th year of the Chiwu era (238–251) in Sun Quan's reign but did not state his age at his time of death so his birth year cannot be determined. Quote from Sanguozhi vol. 60: (十二年卒， ...) However, the Jiankang Shilu mentioned that Quan Cong was 52 years old (by East Asian age reckoning) when he died, so, by calculation, Quan's birth year should be around 198. Quote from Jiankang Shilu vol. 2: ([赤烏十二年]冬，右大司馬全琮卒。琮字子璜， ... 卒，時年五十二，帝流涕。)
