About banquets: I'm not sure about your customs there. It's hard to decide. My suggestion is that you and your husband serve tea to your parents together. Your husband's parents are not required to attend the door-to-door banquet, but your father's birthday will be attended. If the schedule is good, I suggest that your husband's parents come, and your friends and classmates should also be invited (depending on the local customs, if my suggestion conflicts with the local folk customs, it is more important to follow the folk customs).
