I went to Shaanxi for a trip. I came to Yan'an at night. I came out for food. I walked and came to Erdao Street Food Street. Unexpectedly, I didn’t expect that in the winter of the Great Northwest City, the outdoor food street was still so lively. When I arrived, I had passed the normal dinner time period. At that time, there were not many people on the street, and the more food was eaten late. There were temporary food stalls on both sides of the street. There was a small stall. There was no variety of food. Spicy, light, northeast, Cantonese, everything.
