Where did the Hakkas in Meizhou move in?

Hakkas, also known as Heluolang. Hakka is a distinctive Han nationality, and it is also one of the most widely distributed and far-reaching Han nationalities in the world. Hakka ancestors originally lived in the north, and later moved to the south of the Yangtze River, where they lived in Jiangxi, Guangdong, Fujian, Hunan, Taiwan and Qionglai provinces, and gradually spread abroad, spreading all over the world. From the Song Dynasty, the Han people in the Central Plains moved southward in a large scale and arrived in Meizhou through Gannan and western Fujian, and finally formed a relatively mature and stable Hakka family. Since then, Hakkas have taken Meizhou as their base and moved abroad to the whole country and even all over the world.
