Shanghai people and health

A foreigner, who came to Shanghai alone, wanted to live in Shanghai for a year, without working or accepting alms from others. On the premise of not affecting your health, you must have 40 thousand to 50 thousand yuan. First of all, the minimum monthly rent is 1500, and one year is 18000. Secondly, water, electricity and coal should be at least 100 yuan per month, plus three meals a day. Everyone knows the price in Shanghai, and 2,500 yuan a month is still necessary, so you must prepare 40,000 to 50,000 yuan.
