My friend said that when a man travels to Northeast China, there's only one destination—Changchun. They say that once you get into a taxi, you're already part of the industry chain, and you can get to whatever you want to do extremely fast. So my friends from Changchun, is this true? Are there really couches in the bathrooms of commercial KTVs? Do people really line up outside the bathroom door? I've never seen such a thing—how fun can it really be?!
