There is a big family named Zhao in Tochigi Town. Every autumn harvest season, the family will hire many long-term and short-term workers to work in the fields. One autumn harvest season, Zhao invited a cowherd to cook mung bean soup temporarily to let the workers quench their thirst. Unexpectedly, the inexperienced cowherd put too many mung beans, and the result became a pot of porridge. Fearing that he would be scolded by his master, he "drained" a lot of cooked mung beans, mixed them with glutinous rice and steamed them into cakes. The shopkeeper gave it to the workers, who had never seen this food before. After eating it, they felt that although it was smooth, they still felt something was missing. So it was suggested that Baer should be fried in the oil pan, and the cowherd should be fried in the pan accordingly, and then taken out to taste. Everyone praised it and named it "Fried Bayer". Later, the shopkeeper took some to the teahouse for everyone to taste, and people made some suggestions on its ingredients. The unique fried rice cakes gradually blossomed and were introduced to the people.

At that time, Tochigi Town was an important town in Neijiang of Tuojiang River, with developed shipping and the only place for Chengdu-Chongqing land transportation. People come and go every day, so lively. A few years later, the settled cowherd has a large passenger flow on weekdays, and sometimes he will set up a thatched shed and a cooker, and use the "Banqiao" made of three big boards (where fried rice cakes are now operated) to operate fried rice cakes. Because it is easy to carry, it is also beneficial for pedestrians to hurry and do business. People call it "Banqiao fried rice cake".
