Because Hakka people live in many ethnic groups, they often have several clans with the same surname. The whole family name, the tradition has unwritten clan rules. Any major event that damages the reputation of the surname shall be resolved through consultation by the whole surname. If you fight with a foreign surname, every household will go out to solve it to prevent losses. Most Hakkas don't do it without authorization. If they are reasonable, they will argue with each other. If they are unreasonable, they will settle it amicably. Anyone who dares to violate the clan rules will be isolated by his people. Whenever pigs are killed, Hakkas will hold a banquet to entertain their people. Each household in the small village invites one person, and the big village invites prestigious old people and brothers living in the house. Once someone in the family is admitted to a technical secondary school or university, or joins the army or goes out to work, the Hakka people will hold a banquet for the brothers who come to congratulate. In order to maintain the unity of the clan, after the woman has passed the house, she usually lives together for three generations and four generations, if there are brothers and sisters under the man. The bride and groom must live with the elderly for a period of time before they can divide the kitchen. Even if you don't live in the same kitchen with the elderly, you should bear the obligation to support the elderly and raise your siblings. Otherwise, it is regarded as the inverse son. After the kitchen is divided, whenever there is good wine and good food, we should invite the old people to eat together or cook them a dish.

Because the family is valued, the elderly are highly respected. When eating, the old man's seat faces the gate to show respect, which is the custom of Hakka people. Adults sit on both sides, and children can only sit on the side facing the old man. If there are too many people in the family, men sit at a table and women sit at a table. When eating, children should take the initiative to help the elderly with food. When children help the elderly to add rice, they must carry bowls with both hands. When the old man is talking, the child can't interrupt or make any noise. After dinner, children should say "eat slowly".

In family customs, the birth of a child is highly valued. Hakka children were born in three dynasties. Grandma, sister-in-law, brother-in-law (sister-in-law) and married women wrapped eggs with bamboo radishes and came to the new delivery room to do the "Three Dynasties". Half a month later, grandma invited more women, carrying sweet wine, eggs, rice and hens to her nephew for "half a month", commonly known as "eating ginger wine". This banquet is the most lively. After the child has a full moon, grandma asks a woman to make a "full moon" for her nephew (or niece). Hakkas generally live less than a year.
