At that time, Qin Shihuang ordered the army to attack Baiyue area (now the southeast coast). For strategic needs, Qin Jun wants to build a Lingqu in the area north of Guilin. Because most of the Qin soldiers are northerners, they have formed the habit of taking pasta as their staple food. In a foreign land, the staple food has become all kinds of rice, and many soldiers have no way to adapt. In order to overcome the problem of eating, Yu Shilu, the official in charge of building the Lingqu at that time, came up with a good idea. It is said that Shilu comes from Vietnam (southeast coast). He ordered the cooking squad of the army at that time to swell, grind and steam the rice and make it into strips for the soldiers to eat. After eating it, Qin Bing liked it very much and remembered the taste of his hometown. Thus, Guilin rice noodles were born.
No matter the origin time of noodles or rice noodles in Guilin, there is the same doubt, that is, noodles, as a food form, are ground with a turntable stone mill and processed later. But it was not until Qin Shihuang unified the six countries that the turntable stone mill began to appear in China. Moreover, the earliest appearance of thin wheat in China was in the Eastern Han Dynasty, which was more than 300 years later than the legendary Qin Shihuang period. So we can better judge that the invention time of Chinese noodles should be hundreds of years later than the legendary one.
Anyway, noodles, as a common food today, have various practices, such as Longxu Noodles in Fujian, Daoxiao Noodles in Shanxi and Xiaomian in Chongqing. These practices are deeply loved by the masses and will be passed down in the long history of China's food culture.
