Why do Qufu people say goodbye on their birthdays?

The saying that Qufu people "give up excessively" on their birthdays may come from ancient records and traditions. Qufu, Shandong Province, the birthplace of ancient Confucius, has the custom of longevity on the third day of the first month, usually 73 years old. On this day, relatives, friends and neighbors will celebrate their birthdays in advance, which is called "warm birthdays". The old man who received the gift sat in the hall, accepting congratulations and gifts. Then, people * * * drink Shoujiu and eat Shoumian, and hold some ceremonies symbolizing longevity, such as whole chicken with vinegar and kowtowing to "Shouxing Chicken". These traditional customs have been passed down from generation to generation, and gradually formed the current saying of "abandoning".
