It is said that a long time ago, there was a scholar who was studying hard in the central pavilion of Nanhu Lake, Yunnan Province, and his wife had to cross a bridge to deliver meals to the scholar every day. One day, the wife thought that her husband was very hard, so she stewed a chicken and put it in a clay pot to give it to her husband. However, something happened halfway, and it was delayed. When she came back, she found that the chicken in the clay pot was still hot. When she opened it, she found that there was a thick layer of butter on it, so she cooked rice noodles with chicken oil for her husband. After eating, the scholar was full of praise. Because his wife has to cross the bridge in Nanhu every day to deliver meals, the scholar named it "crossing the bridge rice noodles".

Crossing the bridge rice noodles has a history of more than 1 years. Originated from Mengzi in southern Yunnan. Legend has it that the old scenery of Nanhu Lake in Mengzi County is beautiful, and there are often literati attacking books and reading poems here. There is a Yang Xiucai who often goes to the Huxin Pavilion to study, and his wife sends every meal there. Scholars study hard, often forget to eat, and even often eat cold rice and cold dishes, and their bodies are getting tired. His wife was anxious and distressed, so she killed the hen at home, stewed it in a casserole and sent it to him. When she went to collect the dishes and chopsticks again, she saw that the food she sent was intact, and her husband was still reading a book. I had to take back the food and reheat it. When she took the casserole, she found it was still very hot. She uncovered the lid. It turned out that the surface of the soup was covered with a layer of chicken oil, and the clay utensils did not transfer heat, so the heat was sealed in the soup. In the future, his wife will use this method to keep warm, and some rice, vegetables and meat slices will be cooked in hot chicken soup and served to her husband while it is hot. Later, many people imitated her innovative cooking, and the cooked rice noodles were really delicious. Because Yang Xiucai had to go through a small bridge from home to the pavilion in the middle of the lake, everyone called this way of eating "crossing the bridge rice noodles".

After continuous improvement and innovation by chefs of Yunnan flavor in past dynasties, "Crossing the Bridge Rice Noodles" enjoys a growing reputation, enjoying a good reputation at home and abroad, and has become a famous snack in southern Yunnan.
