Jixi's specialty snacks are Korean specialty foods. The noodles are thin and tender, with sweet and sour cold noodle soup, which makes people memorable. I have the opportunity to invite Jixi to taste them. Cold noodles are traditional Korean food. They are made of buckwheat noodles or wheat noodles (also corn noodles, sorghum rice noodles and elm bark noodles), starch and water, and then pressed into round noodles. Soak it in cold water after cooking, then remove the cold water with seasonings such as beef slices, peppers, pickles, pears or apples, soy sauce vinegar, sesame oil, etc., and add beef soup. In the past, Koreans had the tradition of eating cold noodles at noon on the fourth day of the first month, or on their birthdays. According to folklore, eating slender cold noodles on this day indicates longevity and longevity, so cold noodles are also called "longevity noodles".
