Thirty-seven men have been arrested on charges of being part of a homosexual prostitution ring in Haizhu, Guangzhou. The men were caught after police raided the Male Hero Health Centre at Tongqing Mansion on Tongfudong Street. The manager of Tongqing Mansion, Liao Nushi, claimed that when the mansion opened this February, he was unaware that a male prostitution business was being conducted on the premises. 'We weren't too clear what this 'Hero Centre' was,' Mr Liao was quoted as saying in yesterday's Beijing Youth Daily. 'All we knew was that it was a sauna and a bathhouse.' A male reporter who visited the Hero Centre undercover said he paid a 55 yuan (HK$51) entry charge at the door. He was then asked if he needed servicing, and was given the opportunity to select the young man of his choice. Afterwards he was given a list of prices in the range 200-500 yuan for a miscellany of sexual acts. At a Guangdong province police station one young man explained the success of the business. 'When we opened up the centre, it was just to make money,' he said. 'But we soon realised that there was tremendous demand. The 100 membership cards we had printed up before the opening were all gone in less than a month.' According to the centre's legal representative, all of the suspects are still in police custody. Prostitution and pornography, involving either men or women, are illegal under mainland law. But there is no law banning homosexuality.
