When did the Han nationality in Liangshan Prefecture move here? Where is your ancestral home?

Han people have lived in Liangshan since Qin and Han Dynasties. The earliest celebrity associated with Liangshan was Sima Xiangru. He crossed the Lishui River, built a bridge in Sunshui, got through Lingguan Road and established Guangdong-Hong Kong County. Since then, Liangshan has been under the rule of the central government. Liangshan has been inhabited by Han and Yi people since ancient times. The Han nationality occupies the valley plain area, and the ethnic minorities are high mountains. Of course, there are many Han immigrants in history, and the primitive Shu people are probably more precious than the pandas today. Liangshan, like Sichuan as a whole, has an absolute majority of immigrants from other provinces. The ancestral homes of the Han people are in the north and south, almost everywhere, except Tibet and Xinjiang of course.
