Apparently, the pimps were trying to drum up business and offered lower-rate encounters, police said. It operated out of a ping-pong hall -- the Robo-Pong Training Center, the New York Post reports.
The men would try to lure students to the Robo-Pong Training Center by distributing business cards outside the school, sources said. The cards were printed only with a contact number, an image of a topless woman - and a word, "Good."
Zheng and Liuchang allegedly recruited immigrant women off the street to peddle flesh in hidden rooms at the center, whose hours were posted on a sign adorned with rulers and pencils and the words "School Days."
