Hello! I'd like to know if there are places such as Tesco, Walmart Or Carrefour in Lanzhou?

Well, as I know, there is no Tesco, Walmart or Carrefour in this city. But don't worry. You are suggested to go to Vanguard Supermaket (biggest chain supermarket in town). There are many branches. One is located at No.189, East Hezheng Road, Chengguan District. You can provide your living place first. Then I can find the nearerone for you.
