When I arrived in Lanzhou, there was no reason not to eat beef ramen. After eating the authentic Lanzhou ramen, I realized that the standard of other places is really not a little worse, but a lot worse. Friends in Shanghai can go to the "Dunhuang Building" on Changning Road to experience the more authentic Lanzhou ramen. My main event in Lanzhou was in Xigu. Due to limited time and traffic congestion, I went around the back mountain of Xigu. Because of the plateau, I was a little breathless. However, the air on the mountain is fresh, the sky is blue and white, and some surrounding residents are seen barbecue and picnic on the mountain with chairs and food prepared by themselves. It is so uncomfortable! Escape the depressed life in the grid, and relax in the fresh air under the mountain. It is really like paradise.
