If you go to Lanzhou to learn the practice of "authentic Lanzhou beef noodles", there are many places, including folk masters with apprentices and beef noodle classes. But in Lanzhou, there is no name "Lanzhou Lamian Noodles", so the name is not authentic, let alone authentic craftsmanship.

When you arrive in Lanzhou, you can look at the Lanzhou Evening News, which has an advertisement for the enrollment brochure of the beef noodle class. It seems that the well-known and large-scale one is New Oriental Vocational and Technical College. To say the most authentic, you still have to learn from the chef in the noodle restaurant!
