Jia directed me to some news from Lanzhou (article in Chinese, with pictures). It seems that university students are now flocking to Moba (摸吧) or touch bars. At these bars, the patrons pay ten kuai to feel up the xiaojies for three songs (the patrons don't get to choose the songs). There is supposedly no sex involved, but the patrons get to let their hands roam wherever they please.
No word on if these touch bars have migrated south to Shenzhen.
