How should the elderly spend their 66th birthday? Is there any tradition?

In the north, people over 66 are particular about eating girls' meat.

On the parents' 66th birthday, the married daughter goes back to her parents' home to pay New Year greetings, and a piece of meat is indispensable as a birthday present. This piece of meat means that the daughter is a piece of meat on her parents. When she grew up, she bought meat to repay her parents' kindness. Although it is bought meat, it also symbolizes cutting your own meat. When buying meat, you can't care about the amount of meat. Be sure to cut it with a knife to show children's respect for the elderly. Some children buy six catties and six taels of meat for their parents' birthdays, and steam six or six steamed buns for the elderly to eat. Others are not allowed to share them, otherwise it is called "grabbing happiness".
