Now it is generally enough to offer tea to both parents. However, according to the previous custom, tea will be served to grandparents, uncles, aunts, uncles, brothers and sisters and cousins in the order of generations. When offering tea, the couple should hold the cup in their hands, bow their upper bodies, and stretch the cup forward to their parents' chest 40 cm, so that their parents can hold the cup with their hands. Moreover, never serve tea with one hand for convenience, and never put your finger on the mouth of a teacup or soak it in tea. These are all very impolite.
