Is there a black light dance in Guangzhou now?

In Guangzhou, next to China World Hotel and Zengcheng District, black light dance means that the brightness of the light is within 5 lux. More vividly, it means that the dancers can't see each other's faces clearly within one meter. Because the black dance is performed when the dance is four steps slow, the black dance is actually a two-step dance, or a face-to-face dance. In order to pursue economic interests, a few ballroom operators artificially cater to the requirements of some customers' low taste and illegally operate black light dance in disguise. In their view, the guests who go to the ballroom for consumption are all directed at some ulterior psychological or physical needs. Therefore, the phenomenon of black light dance has not been completely eliminated.
