Is the Sun family in Longcheng really fake?

18-year-old official Sun Shi moved to Shaanxi. Born in Hongdong, he immigrated in the early years of Hongwu in Ming Dynasty. When they moved out, eighteen uncles and brothers, according to the immigration practice, gathered with their families in front of the big locust tree in the suburb of Hongtong to say goodbye. Then he moved to Henan, where several people were separated and settled in Shandong, and then spread all over Sulu, Henan and Anhui.
