Historical Origins

During the period from the Two Jin Dynasty to the Tang and Song Dynasty, due to war and chaos, the Han Chinese in the Central Plains of the Yellow River Valley were forced to migrate southward, and after five major migrations southward, they settled in Guangdong, Fujian, Jiangxi, Hong Kong and the New Territories in the south. Because they left their native land in the Central Plains, these southward-migrating Han Chinese have always called themselves "guests" to mean that they are living in other places.

Ancient local officials for these immigrants registered in the household registration, also set up for the "Hakka", known as "customer", "Hakka", which is the origin of the Hakka people. In order to prevent foreign enemies and wild animals, most of the Hakka people live in clusters, the formation of a dragon house, house, horse building, five phoenix building, earth building, four-corner building, etc., is a concentrated embodiment of the Hakka architectural culture.
