Later, later generations Chen Hesheng, Ma Baozi and others called it "one soup and two whites". Moreover, there are many kinds of noodles, such as "big width" two fingers wide, "two widths" one finger wide, "leek leaves" in the shape of grass leaves, "a nest of silk" as thin as silk thread, and "wheat gluten" with triangular strips. In the following 200 years, Lamian Noodles, a Lanzhou beef, was famous for its bowl noodles, rotten meat, delicious soup and fine noodle quality. It has penetrated all over the country and won the praise and honor of domestic and foreign diners. 1999 was identified as one of the three pilot varieties of Chinese fast food by the state, and it was praised as "the first side of China" and became a wonderful flower in the catering industry.
