Jia county noodle is a unique snack with exquisite ingredients, which has a history of thousands of years, and is called jia county for short. Lehe in jia county is a kind of round food. At first, buckwheat flour was used as cloth. Pepper boiled in pure sheep oil, century-old pot soup and fresh mutton were added, supplemented by more than ten kinds of seasonings such as star anise, fennel, pepper, cinnamon, chopped green onion and medlar. It not only tastes delicious, but also has the functions of warming stomach, dispelling cold, nourishing yin and strengthening yang, and protecting health. In the late Qing Dynasty, buckwheat flour was replaced by wheat flour, which was more nutritious. According to the book "China Flavor Diet", Lehe in Jiaxian County "strengthens the spleen and regulates the stomach, which is the treasure of health preservation". Editor's Note: The historical origin of this passage, called He Lou in ancient times, is also called Huoluo. It is a popular pasta in the north and northwest of China with a long history. As early as 1400 years ago, the ancestors drilled 6-7 small holes with horns, which were as big as thick hemp lines, and the batter fell into the corners to cook noodles. According to legend, during the Kangxi period of the Qing Dynasty, Emperor Kangxi praised its unique flavor after eating it. However, because the homonym of the name "Helou" is not in harmony with river regulation, I am very unhappy, so I changed the name "Helou" to "Lehe". In the early years of the Republic of China, warlords scuffled and the people struggled. A Shaanxi native fled to Jiaxian County, Henan Province, where he started a "Lehe" business. Because of its exquisite workmanship and delicious food, it is deeply loved by the people and eaten by many people. At the end of the 20th century, with the improvement of people's living standards, the production of Lehe in Jiaxian changed from a complicated production mode for thousands of years to a mechanized production, and the condiments were more abundant. On the basis of the original materials, more than ten kinds of traditional Chinese medicine condiments such as cinnamon and medlar are added, and the secret recipe of ancestral ingredients is added, which has the health care and disease prevention effects of warming stomach, dispelling cold, nourishing yin and strengthening yang. Nowadays, jia county businessmen engaged in business are praised by the media as "jia county people" and "jia county people" have spread all over the world.
