It is because there is a legend that a scholar eats rice noodles across the bridge sent by his wife every day and has been handed down from generation to generation.

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 wife often cooked rice noodles for him, but when she left the island, the rice noodles were already cold. When a chicken soup was delivered by chance, Miss Scholar found that the chicken oil covered on the chicken soup could keep the temperature of the soup, so she invented the method of scalding rice noodles in a soup bowl before eating.

Because crossing the bridge to the island is also to commemorate this good wife, it is called "crossing the bridge rice noodle" in later generations.
