Wu County
Wu Jing was from Wu County, Wu Commandery (around present-day Suzhou, Jiangsu) but he grew up in Qiantang County (錢唐縣; present-day Hangzhou, Zhejiang). He was orphaned at a young age so he lived with his elder sister, Lady Wu. After Lady Wu married the general Sun Jian, Wu Jing became a subordinate of his brother-in-law.
