Who invented cold rice noodles? According to legend, when Qin Shihuang was in power, there were100000 mu of paddy fields near Xi 'an. One year, it didn't rain for a long time and the rice fields dried up. The quality of polished rice is too poor to pay tribute to the emperor. When farmers are afraid to cheat the king, they are very anxious and panic. At that time, a farmer named Li Mingshi soaked rice in water, ground it into rice paste, then steamed it on a steamer and cut it into strips, which was called rice noodles. Everyone was amazed after tasting it. Li Twelve came to Xianyang with dough and tribute, and presented the dough to Qin Shihuang. The emperor ate the delicious dough, praised it twice, and ordered that only rice dough could be used as a tribute from Xi 'an. Li XII did a great thing for everyone. Later, on the day of his death, that is, on the 26th day of the first lunar month, every household in Xi 'an would steam rice noodles to commemorate Li XII.
