According to legend, there was chaos in the Qin and Han Dynasties, and Liu Bang was king in Hanzhong. In order to make the country prosperous, he ordered Xiao He to build the He Shan Dam, where water conservancy was built and a bumper harvest was achieved every year. In order to improve their lives, farmers constantly explore and develop new foods. They dilute flour with water, steam it into pancakes, then cut it into strips and eat it with hot sauce and other cold dishes. It's delicious.
In order to observe the people's feelings, Liu Bang often visits privately. One day, Liu Bang came to a family, and the hospitable host entertained Liu Bang with this new dish. Liu bang didn't 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 production method again. Liu Bang laughed and said, "This is steamed bread."
With the passage of time, the eating method of cold noodles is also improving. People began to use overlapping steamers, which can steam many sheets at a time, and explored a new method of washing out gluten and soaking rice, grinding it into rice slurry and steaming it. Steamed cold noodles are big and thin, with elastic tendons, and cut into thin strips. Just like pimps, they are gradually renamed as "dough" (and also called "dough" and "dough" according to different raw materials).
During the reign of Kangxi in the Qing Dynasty, there was a Zhang in Hanzhong who served as a county magistrate in Ruyang, Henan. One year, the imperial court sent an imperial envoy to inspect Ruyang. The shrewd Zhang Zhifu did not prepare a banquet, but hosted an imperial envoy with the unique flavor of his hometown. The imperial envoys ate too many delicacies and got greasy all the way. When they ate this bean jelly, their appetite suddenly opened up, as if in heaven. Then he asked how to do it, and Zhang county magistrate told him one by one. Shortly after the imperial envoy returned to Beijing, Zhang county magistrate was promoted to magistrate. Everyone didn't know why, and then unanimously guessed that the dough of a meal was favored by an imperial envoy, but later pleaded with the holy one and was promoted.
This story was sent back to Hanzhong and became a generation of stories. The people nicknamed it "the thin-skinned magistrate". Unfortunately, the imperial envoys forgot the making method or other reasons, and Beijingers still couldn'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 cold rice noodles have become the first of the four unique flavors in Hanzhong.
