SHANGHAI, China (CNN) -- In between selling tickets and greeting customers, Min Min turned his curvy 6-feet-tall frame to survey the spacious dance hall and revealed he is no ordinary doorman at this extraordinary place.

"When I first started this, it was only a dozen or so of us," reminisced the former factory worker-turned-drag queen.



"Now 300 people or more come each night."



Welcome to Lai Lai Dance Hall, arguably the only entertainment venue for older gay men in Shanghai, if not the whole of China. Tucked away in a rundown neighborhood in the city's northeast, Lai Lai sits atop a public bathhouse, and features cracked wooden floors and a primitive sound system.



Its location and facilities, however, belie its prominence in a community that thrives almost entirely underground.



Every weekend, men flock here to unleash their ballroom dancing skill as well as their true identities for three treasured hours. Lai Lai's "gay nights" are only on Fridays, Saturdays and Sundays.



Casually dressed in jeans and sneakers, men of various ages -- but mostly in their 40's and upwards -- and shapes filled the dimly lit dance floor one recent evening. They waltzed, jitterbugged and rumbaed in pairs to the nostalgic Mandarin tunes churned out by a live band on the small stage.



"You won't see this anywhere else," said Min, organizer of this regular gathering, himself a middle-aged gay man whose dual passions lie in ballroom dancing and performing in drag.



On this Sunday night, however, he was out of drag, donning a sweater and cargo pants. "I don't really do this for the money -- it's just great fun."



Patrons pay a mere 5 yuan (70 U.S. cents) to enter and enjoy cheap drinks -- a bottle of beer costs just 3 yuan.



Observing from the sidelines, one of Min's fellow drag queens -- known as Teacher Zhang -- noted most older gay men don't feel comfortable going to the more expensive bars or clubs frequented by the younger generation.



"It's a totally different culture and environment in those places, while everyone fits right in here," said the 58-year-old former soldier and retired school administrator.



"It's a rare outlet for people to relax, to find friends or sex."



Zhang's personal story mirrors those of many patrons at Lai Lai. Realizing he was gay at an early age, Zhang -- like many gay men in China -- married a woman because of family and social pressure. He is expecting to become a grandfather this autumn.



"My wife and my son have suspicions about me, but it's always going to be a question mark in their minds," Zhang said.



"They have seen me perform folk dance in drag, but I will never let them see me in an intimate situation with another man."



Unlike many among Lai Lai's largely blue-collar clientele, Zhang said success in running his own catering business has injected freedom and flexibility into his closeted life.



"I bought a big duplex for my wife, and I told her I would stay in the old apartment to concentrate on work," Zhang said.



"Chinese women at her age are very pragmatic -- they are satisfied as long as you take good care of the family."



Taking precautions



Family issues aside, activists have pointed to inconsistencies in government policy to explain older gay men's reluctance to come out.



Although homosexuality is not illegal in China and has been removed from the country's list of officially recognized mental disorders since 2001, it remains a taboo topic in the state-run media.



Gay venues have popped up in major cities across China in recent years, but the authorities sometimes shut them down during politically sensitive times.
