In the Warring States period, the Chu state covered most of present-day Hubei and Hunan, the areas that would form Jingzhou in a later era. The Qin state dropped the name "Chu" and used "Jing" (荊) instead to avoid a naming taboo, since the personal name of Qin's King Zhuangxiang (281–247 BCE) was "Zichu" (子楚; lit. "son of Chu") because his adoptive mother, Lady Huayang, was from Chu. Chu was conquered by Qin in 223 BCE in the final stages of the Qin unification campaign.
