Generally speaking, the big etiquette is to send pig's trotters (whole legs), birthday noodles (noodles) and eggs to peace at the end of the year. In the local dialect, it is called "Happy Birthday", which can be sent by any family, preferably by your parents themselves.

During the Spring Festival, find a good day (auspicious day), let your parents visit your home, bring some auspicious gifts casually, and then invite your parents-in-law to visit your mother's home.
