The historical origin of eating longevity noodles
According to legend, Emperor Wu of the Han Dynasty chatted with ministers one day. When talking about people's life span, Emperor Wu said: According to the image number, a person's life span is long. If he is 1 inch long, he can live to 100 years old. "Minister Dong Fangshuo laughed after hearing this.
Emperor Wu of the Han Dynasty asked him what he was laughing at and explained, "People live 100 years old, of which 1 inch is the length. Peng Zu lived 800 years and was eight inches long. How long is his face? " Everyone laughed, but they could think of a flexible way to express their desire to live a long life.
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". Generally speaking, there is only one noodle in the whole bowl of longevity noodles. You'd better not break it when you eat it. This custom has been passed down to this day.
