How much can I earn by doing foot bath in Shanghai for one month?

I tell you, many pedicure shops in Shanghai have a guaranteed price of 4,000 to 4,500, and girls have a guaranteed price of 5,000 to 5,500. The commission is about 35 per hour, and the essential oil massage is about 55 to 70. There is no tip here, but you don't have to pay one or two thousand admission fees like Shenzhen, and Shanghai doesn't have to pay admission fees. Are you a man?
