There are various stories about cold rice noodles in Hanzhong, but the following story about the origin of cold rice noodles is the most popular.

According to legend, during the Qin and Han Dynasties, there was great chaos in the world. Liu Bang claimed the title of king in Hanzhong, and ordered Xiao He to build the Shanhe Dam in order to make the country prosperous. The water conservancy was prosperous and the grain was harvested year after year. In order to improve their lives, farmers are constantly exploring and developing new foods. They dilute the flour with water, steam it into pancakes, then cut it into strips and eat it with hot sauce and other cold dishes. It tastes delicious.

Liu Bang often travels incognito to observe people's feelings. One day, Liu Bang came to a family, and the hospitable host entertained Liu Bang with this new food. Liu bang did not eat it, but once he ate it, he was full of praise. After eating it, I was so excited that I wanted to know its name, but the farmers couldn't say it for a while. Liu Bang asked the method of making it again. After listening, Liu Bang laughed and said, "This is steamed cake."

With the passage of time, the eating method of cold rice noodles has been constantly improved. People began to use overlapping steamer, which can steam many sheets at a time, and explored new methods of washing out gluten and soaking rice, grinding it into rice slurry and steaming it. The steamed cold rice noodles are big and thin, and the tendons are flexible. Just like pimps, they are gradually renamed as "dough sheets" (and they are also called "dough sheets" according to different raw materials.

During the reign of Emperor Kangxi in the Qing Dynasty, there was a Zhang in Hanzhong who was a county magistrate in Ruyang, Henan. One year, the imperial court sent an imperial envoy to inspect Ruyang. The shrewd magistrate Zhang did not prepare a banquet, but served the imperial envoy with the special flavor of his hometown. The imperial envoys ate too many delicacies along the way, which made them greasy. When they ate this cold rice noodle, their appetite suddenly opened up, and be in heaven.

I asked about its production method, and Zhang County Order told me one by one. Shortly after the imperial envoy returned to Beijing, Zhang County Magistrate was promoted to the position of magistrate. Everyone doesn't know why, and then unanimously guessed that it was probably a meal of dough that won the favor of an imperial envoy, but later appealed to the holy family and was promoted.

this story was reported back to Hanzhong, which became a generation-old story, and the people jokingly called it "the magistrate with a thin face". It's a pity that the imperial envoys have forgotten the making method or other reasons, and Beijingers still can't make cold rice noodles. Hanzhong people's skills in making cold rice noodles are getting higher and higher, and the methods of making cold rice noodles are constantly improving, and the ingredients and seasonings are becoming more and more particular, so the noodles have become the first of the four unique flavors in Hanzhong.
