Are the aborigines in southern Fujian She nationality?

In ancient times, it was the Min and Yue ethnic group (a branch of Baiyue). During the Jin and Tang Dynasties, the immigrants from the Central Plains came to Zhangzhou, Quanzhou to slaughter, basically killing all the men in Fujian and Guangdong, leaving a small number of them to become the She nationality now. Fujian and Vietnamese women merged with Han Chinese to become Hakkas. The Han people in the Central Plains stayed in southern Fujian without integrating the Mongols in the Yuan Dynasty and the Manchu in the Qing Dynasty, and kept the cultural customs of Heluo (ancient Central Plains Han people), so the Han people in southern Fujian were called Minnan people, also known as Heluo people.
