I would like to ask the source of Liu's surname in Dingyuancang Town, Anhui Province. According to my grandfather, he was forced to move to Dingyuan, Anhui Province from Jingdezhen or Tianjin in the Qing Dynasty. Later, the people surnamed Liu who went to Shanghai moved to different places: during the Xining period in the Northern Song Dynasty, Liu Ruxu moved from Shanghai to Gu Chi to gather wind and make a career. At the end of Yuan Dynasty, Liu You's 17th grandson Liu moved to Dongxiang Social Department. A few years later, later generations sent Yan Luling to Tanghuang Caojie Bridge and downstairs, Tanghu, Changde and Yuanjiang in Hunan, Daning and Dingyuan in Sichuan. In addition, Liu also has a melon-Tian Xin in She County, which is also Liu's successor. The descendants of Liu in Shanghu also migrated to Shaoguan, Zengcheng, Boluo and Huangjiashan Township in Dongguan.
