What about Jianyang? Was Kangxi a descendant of Xu who immigrated from Changle County, Guangdong Province during the Qianlong period?

This genealogy is actually the unified genealogy of the Xu family in Dazhu, and each branch is the ancestor of the first generation of the Ming Dynasty. Xuanzu was born in Xinhui, Guangdong Province, and was born in Lingui County, Guangxi in the last years of Hongwu. After his tenure, he settled in Lechang County, Shaozhou County, the capital of Jiu Feng. It was spread to the 12 jade symbol (during the reign of Emperor Kangxi of the Qing Dynasty, he came to Sichuan with his son and settled in Gaojiachong (Imashimizu Town). The descendants of the 12th generation Yu went to Sichuan and lived in Xujiacuo (present-day miaoba town). Jade Song, the son of the 12th, went to Sichuan to live in Xujia 'ao (present-day miaoba town). Wen Kui, the 12th generation, took his son into Sichuan during the reign of Kangxi and lived in Xujiaba (now Huangtan Township). The genealogy contains a textual research on the origin of Xu in Guangdong, a textual research on the origin of Xu in Sichuan, a genealogical table of Duluo in Guangdong and a genealogical table of branches of Dazhu. Does Jianyang know? Those who moved from Guangdong seem to be right at the same time. Hope to adopt.
