General Wang Jian of Qin Dynasty. Is that Wang Xing?

Maybe it's the Wangs in Tianshui County. Wang Xing comes from Ji surname, Zi surname, etc. In the Western Zhou Dynasty, a prince was abolished and his descendants changed their surname to Wang. After Bigan was killed in Shang Dynasty, their descendants also changed their surname to Wang. They changed their surnames to Wang because they are all descendants of the royal family. Taiyuan County, Jingzhao County, Tianshui County, Chenliu County, Hedong County and other famous Wangs. Hedong County and Tianshui County are descendants of Bigan. Tianshui and Pingliang are adjacent now.
