Hakka is a branch of the Han nationality, with remarkable characteristics, and it is also one of the widely distributed and far-reaching nationalities in the world. Starting from the Yongjia Rebellion in the Western Jin Dynasty, Han residents in the Central Plains moved southward on a large scale, and arrived at the junction of Guangdong, Jiangxi and Fujian, where they mixed with local aborigines and intermarried with each other. After thousands of years of evolution, a relatively stable Hakka clan has finally formed. Since then, the Hakkas have taken Meizhou as their base and moved abroad in large numbers to various provinces in South China and even around the world. The four Hakka States are Meizhou, Ganzhou, Tingzhou and Huizhou. The stone wall in Ninghua, Fujian is the center of Hakka legend, and it is called "Hakka ancestral land".
