In the eyes of ordinary people, Hakkas are immigrants, a branch of Han immigrants from the north to the south. In the long years, they have been displaced from place to place and experienced hardships, forming, evolving and developing into a large clan with a population of tens of millions.

Hakka customs generally include national traditional festivals, local sacrifices and rituals. These mainly include traditional festival customs, wedding customs, Japanese favorite customs, Hakka wine customs and so on. Because there is a lot of content, it is not clear here. I'll give you two websites with detailed descriptions, hoping to help you.
