The folk custom of eating noodles on birthdays has a long history. This custom originated from the Western Han Dynasty. According to legend, Emperor Wu of the Han Dynasty believed in ghosts and gods and physiognomy. One day, when talking about people's life span, Emperor Wu of the Han Dynasty said: According to the number of images, the longer people are, the longer their life span will be. If he is 1 inch long, he can live to 100 years old. "Dong Fangshuo, the minister sitting next to Emperor Wu of Han Dynasty, burst out laughing. All the ministers were puzzled and accused him of being rude to the emperor. When Emperor Wu asked him what he was laughing at, Dong Fangshuo explained, "I'm not laughing at your majesty, but at Peng Zu. People live 100 years old, and people are 1 inch long. Peng Zuhuo is 800 years old and his people are 8 inches long. How long is his face? " Everyone laughed when they heard it. It seems impossible to live a long life with a long face, but you can think of a flexible way to express your desire for longevity. The face is the face, and the kind of "face length is face length", so people borrow long faces to wish longevity. Gradually, this practice has evolved into the habit of eating noodles on birthdays, which is called "longevity noodles". This custom has been passed down to this day.

On the birthday, family or friends hold a banquet to celebrate their birthdays. After all the banquet dishes were served, we began to eat. Everyone put a bowl of noodles for the birthday party, which made them happy. Everyone also took a noodle from his bowl and put it in the bowl of the birthday party, which means "prolonging life". The noodles in the bowl will generally be filled according to the amount of food eaten at the birthday party and the amount of drinking and eating. Basically, everyone adds a bowl.
