Son-in-law Day
There is still a lot of food left over from the celebration of "God's Birthday" on the ninth day of the lunar month, apart from eating it for one day on the tenth day of the lunar month. Therefore, the mother's family does not have to spend any more money, so they use the leftover food to entertain their son-in-law and daughter. The folk song is called "Eleventh Day"
Invite your son-in-law."
In fact, "Son-in-law Day" has a very historical origin. In ancient times, the leftover food to celebrate the birthday of "God" on the ninth day of the first lunar month had not yet been eaten, so these delicacies that had been sacrificed to the gods were used to entertain daughters and sons-in-law as a first day.

On the eleventh day of the first lunar month, when a daughter and her son-in-law rush back to their parents' home, their elder brother or younger brother must go out in advance to greet them to show their respect and attention to the son-in-law.
