Li Heng 李衡

Sun Xiu, the sixth son of Sun Quan, was enfeoffed as Prince of Langya in the 1st month of the 2nd year of Taiyuan (252) and lived at Hulin. In the 4th month of that year Sun Quan died and Sun Xiu's younger brother Sun Liang succeeded to the throne; Zhuge Ke, who held power, did not want the princes to be in the military strongholds along the Yangtze, and moved Sun Xiu to Danyang Commandery. When Li Heng, Administrator of Danyang, repeatedly harassed Sun Xiu on various pretexts, Sun Xiu petitioned the throne asking to be moved to another commandery, and an edict moved him to Kuaiji. Records, Wu 3 §20

Several years later, when Sun Liang was deposed, Sun Chen sent men to receive Sun Xiu, and Sun Xiu took the throne in what was the 3rd year of Ganlu (258) of Wei, proclaiming a general amnesty and changing the era name. Records, Wu 3 §21 · 23

On the day renwu of the 10th month, in winter of the 1st year of Yong'an (258), Sun Xiu issued an edict granting offices and titles to Sun Chen and the others who had received him. He issued another edict saying that Li Heng, Administrator of Danyang, had given himself up to the officials in charge because of the suspicion arising from past events, but that shooting the belt hook and cutting off the sleeve had each been done for the lord of the time, and ordering that Li Heng be sent back to his commandery and not be made to harbor misgivings. Records, Wu 3 §24–25

These two passages are the only places in Chen Shou's main text where Li Heng appears. His courtesy name, his origin, when he became Administrator of Danyang, what became of him afterward and his death are not recorded, and the Records contain no assessment of him either. Records, Wu 3 §20 · 25
