It is because of the legend that a scholar ate rice noodles sent by his wife across the bridge every day, which was handed down.

The name of crossing the bridge rice noodles comes from a touching story. A scholar went to the island to study, and the virtuous and hardworking lady often made rice noodles for him to eat, but when she went out to the island, the rice noodles had turned cold. When sending chicken soup by chance, the scholar lady found that the chicken oil covered with chicken soup could keep the temperature of the soup, so she invented the method of putting rice noodles in a soup bowl and scalding them before eating.

Because it takes a bridge to get to the island, and in memory of this good wife, later generations called it "crossing the bridge rice noodles".
