For example, if you want to join a subway store in a large shopping mall in Beijing, how much does it cost to open a shop on the ground floor of the big shopping mall (including the joining fee and the money for the shopping mall) Opening a store of 20-60 square meters costs about 800,000 yuan, of which 450,000 yuan of subway equipment is imported from the United States, which is a bit expensive, and the remaining rent and other expenses are about120,000 yuan, and the initial fee10,000 dollars. I consulted the Shanghai Metro Headquarters and later gave up.
