It's best to go to Beef Lamian Noodles School. I recommend a few. There is an oriental technical school in Lanzhou. At the foot of Wuquan Mountain, there are many beef Lamian Noodles training courses in Lanzhou. If you are not far from Wuwei or Liwei, you can go to Wuwei, and there are also many beef Lamian Noodles training courses. Wuwei's is also good. You can go to the beef noodle restaurant to study, but if you have nothing to do, let alone the recipe of soup (in Lamian Noodles, soup is more important than noodles, especially soup). It's best to learn in school, where he teaches you everything from noodles to soup, theoretical knowledge and practical operation, and you can basically become a master of Lamian Noodles!
