I can second that one. I worked there and saw it myself. Very brazen, no concern for local fuzz, and no worries since the local pigs are in on the deal. I personally witnessed at least 10 million RMB in big stuffed bags there per month, as in actual bags full of cash stuffed tight with money hanging out of them. I don't know what the hell they are into with the much loot but I am guessing human trafficking, and drugs. I saw a few whores there with the owner. I never saw guns, but I did see many other weapons. I know for sure there are drugs there but I don't know if that is their gig or a local vendor on site taking some action. I checked into KISQ, and I am glad I did not sign there. That place however is child's play compared to the Ewha scene. Don't go there. Any Korean owned business in China should be avoided.
