"Noodles" is recorded in ancient medical books in China, which started in Guangchengzi and is closely related to the Taoist way of keeping in good health. Pingliang and Tianshui in eastern Gansu are the birthplaces of ancient Huang San, as well as Nu Wa and Kuafu, with a long history of culture. Xuanyuan Huangdi, revered by the Chinese nation as the ancestor of mankind, traveled to the western border after making meritorious deeds, personally climbed the Kongtong Mountain, and asked Guang, who lived in seclusion in Kongtong Mountain, for advice on how to maintain health and govern the country. Is this from Zhuangzi? It is recorded in detail in the chapter of Book of Changes, and Sima Qian, a rigorous scholar, wrote in Historical Records? It is also recorded in Biography of Five Emperors.

According to orthodox Taoism, Guang Chengzi is the embodiment of the old gentleman in the Yellow Emperor era and the first of the twelve golden immortals. "Tai Shang Lao Jun Kai Jing": "When the Yellow Emperor, Lao Jun was a teacher and posthumous title Guang." Legend has it that the immortal is widely known as Xuanyuan people and lives in the stone room in Kongtong Mountain (now Pingliang City, Gansu Province). The Yellow Emperor asked. At that time, Guangtouzi taught Huangdi a volume of natural classics. Huangdi was invited to have dinner with him. Light sword cut down a stout peach tree, hollowed out the straightest section in the middle of the trunk, and drilled many small holes with a brass master's knife, which were as big as thick hemp thread. Then put the peach wood on the hearth pottery, put the dough into strips with a mallet, and drop it into a boiling water pot to cook. Dough is made of wild buckwheat growing near Kongtong Mountain, which is sweet and cold. Modern medical research shows that it is rich in vitamin E and soluble dietary fiber, and also contains nicotinic acid and rutin, which has the functions of lowering blood lipid and cholesterol, softening blood vessels, protecting eyesight and preventing cerebrovascular diseases. In addition, it also has the effects of invigorating spleen, invigorating qi, stimulating appetite, moistening intestines, relaxing bowels, resolving food stagnation, eliminating dampness and lowering qi, and treating intestinal dysentery, gastrointestinal stagnation and chronic diarrhea. In ancient times, people did not invent noodles, but simply called the dough made of grain flour and water "cakes". As a result, this bowl of buckwheat "cake" made widely became the earliest noodle in China. Huangdi, who is used to eating delicacies, big fish, big meat and whole grains, felt warm and refreshed after eating this bowl of "soup cake". Immediately, I asked Guang about "the way of keeping in good health, the principle that the five elements are compatible with each other", how to cultivate one's self-cultivation, the secret of immortality, "being 1,200 years old without getting old" and so on. In the face of the sincere Yellow Emperor, just call a spade a spade: wood makes a fire, fire makes soil, soil makes gold, gold makes water, aquatic wood. Buckwheat belongs to the five elements of wood, and the queen mother who returned to Zhongshan in Jingchuan often eats it. Therefore, it is suggested that Huangdi eat it regularly to "harmonize the five elements, activate the collaterals", which is of great benefit to prolong life. Huangdi praised its unique flavor and remembered every word of advice. He only felt a bright heart, eyes suddenly enlightened. He praised: "Jin Xian Longzhong gave buckwheat the ability to activate its activities, and Ji got a way to govern herself." Say goodbye again. After the Yellow Emperor returned to the palace, he quietly cultivated himself according to the methods widely taught him. Summarize what you have learned into a medical skill-Neijing. And let the chef imitate the practice of Gong Guang during the Cultural Revolution, and often make buckwheat noodles to eat. Word-making Minister Cang Xie also translated the word "Huoluo" into "Lehe". According to legend, Lapras ascended to heaven at the age of 120. Guangchengzi is the first of the twelve golden immortals, under the door of Yuxiu Palace. Therefore, in the folklore of Longdong, there is also an allusion that "Jin Xian traveled in Longdong by crane and Xuanyuan went to Lapras".

Since then, the production method of Lehe cuisine has gradually spread among the people, and then spread to the northern regions, namely Gansu, Shaanxi, Shaanxi, Hebei, Henan, Qinghai, Inner Mongolia and other places. After nearly 5000 years of inheritance and development, noodles have gradually evolved from the original wild buckwheat production to today's wheat flour or corn flour and other miscellaneous grains production. Pork, beef, mutton, tomatoes and eggs are added, which makes the taste better and the auxiliary materials more abundant. On the basis of the original materials, more than ten kinds of traditional Chinese medicines for invigorating qi are added as seasoning, which has the effect of health care. The book "China Flavor Diet" refers to noodles as "strengthening the spleen and stomach, and preserving health as treasure".

Noodles, a bright pearl in pasta culture! Among many kinds of pasta, noodles are a bright pearl in pasta culture. For Pingliang people, the concentration of hometown may be a bowl of noodles. People who wander outside are most concerned about eating this bowl of noodles. When it comes to Pingliang cuisine, we have to say Pingliang noodles. For Pingliang people in the northwest, there is no food to regret the bullying of noodles. Pingliang noodles are slender, tough and refreshing, and can be eaten hot or cold in winter, which has the effect of invigorating the stomach and relieving summer heat. In the countryside, it is not impolite to cook delicious noodles when guests come. Pingliang people have weddings and funerals, and the first bowl of noodles they eat is noodles with stuffing. In the past, a bed made of flour was a necessary cooking tool for every household, but now.
