Hakka is a branch of the Han nationality. Hakka ancestors were originally Han people in the Central Plains. Due to war, famine and government rewards and punishments, they moved to the south. At present, there are more than 100 million Hakkas in the world. Hakka ancestors moved to the south from the Central Plains for five times in total.

Hakka is the only ethnic group that is not named after the region, and it is one of the ethnic groups with wide distribution and far-reaching influence in the world. The name Hakka originated from the guest-giving system in the Eastern Jin, Southern and Northern Dynasties and the customer system in the Tang and Song Dynasties. Immigrants and naturalized people are all incorporated into Hakka, and Hakkas are called Hakkas.
