Mr Lei reportedly ignore the bangs on the door and continued with his high-pitched lover.CCTV footage from the hotel corridor shows a businessman named, Mr Zhang, holder a clothes hanger and kicking at Mr Lei's door in attempt to shut the couple up.
Cameras from the lobby of the hotel in Beihai City in South China show Mr Lei being beaten by the businessman and a number of others.
The violence finally ended after police arrived to mediate the case.
Officers, who said the angry guests were "too impulsive", are said to have allowed Mr Zhang to pay Lei 15,000 RMB (about £1,800) in damages instead of having to begin a civil case.
Mr Zhang paid the amount and no arrests were made.
