DISCOS are still proving to be the most popular nightlife entertainment for the young in Beijing. Dance floors are packed every night in the cheaper, locally run discos, frequented by up to 1,000 revellers who gyrate to music from the '70s, '80s and '90s. JJ Disco manager Su Xinzeng said he had yet to see a potential rival for the industry. 'It is rather difficult for another mass entertainment to offer customers fun for such a low price,' he said. But competition remains keen within the industry. 'The market is not sufficiently regulated and too many organisations can apply to open a disco at the same time,' Mr Su said. He said the peak time was last year when Beijing had about 13 discos. 'But most have been kicked out from the market and there are only three large-scale local discos left,' Mr Su said. Nightman Disco manager Jason Wang Songjiang said their original cover charges when the disco opened in November 1994 were 40 yuan (HK$37) during the week and 80 yuan at weekends. The charges were slashed to 15 yuan and 30 yuan last year to attract more people. Some discos offer free drinks or free cigarettes as a promotional ploy. Inviting overseas or Hong Kong artists to perform, or holding lucky draws on special festivals, are also popular gimmicks. 'We let in for free people who dressed up on Halloween, and gave away a microwave in a lucky draw that night,' Mr Wang said. He said the major problem his operation faced was public safety. 'We have so many people on the dance floors, we must be very careful in guarding for order. 'We have 25 guards who make sure no one smokes on the wooden dance floor.' He said he had heard of drug problems at some Guangzhou and Shanghai discos, but was not aware of such problems in Beijing.
