There is such a loosely organized club in one place in my city. Generally, people who are interested in fighting pay 30 yuan to find a sparring partner (actually being beaten) to play for a few minutes. The average person's physical strength is less than 2 minutes, and wearing gloves, it is difficult to cause substantial damage to a well-trained boxer. Many people who have achieved a little in boxing are deliberately beaten, not for money, but mainly for psychological quality.
