According to the relevant national regulations, all dance halls must be uniformly installed with magnesium light tubes that meet the minimum requirements for ballroom lighting, so as to ensure that the lighting brightness of dance halls reaches the standard. Black light dance means that the brightness of light is less than 5 lux. More vividly, it means that 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.
