Question: Which other cities formerly ruled by Sun Quan belonged to the region conquered by emperor Cao Pi? Passage:In 221, warlord Sun Quan moved the capital of Eastern Wu from Gong'an county, Jingzhou (northwest of present-day Gong'an county, Hubei) to E county (in present-day Ezhou City), and renamed E to Wuchang (literally prospering from military, regarding its logistics role of the military bases established before the Battle of Red Cliffs). Later in the year Cao Pi proclaimed himself the emperor of Cao Wei. Sun Quan declared independence in the following year, and started to build forts and palaces in Wuchang. Sun Quan proclaimed himself the emperor of Eastern Wu in 229, and moved the capital to Jianye. Sun Hao, the emperor of Eastern Wu between 264 and 280, moved the capital back to Wuchang in 265. In 589, the Wuchang commandery was abolished and the Wuchang county was transferred to a new commandery named Ezhou (headquartered in present-day Wuchang District), and remained in the administration since then.
