Diaper or no diaper	穿尿布还是开裆裤？
When it comes to keeping babies' butts clean and fresh, the Chinese have it all figured out. Many toddlers wear pants with slits in them so they can conveniently relieve themselves on the sidewalk or wherever else they happen to be. With China's pollution and environmental problems this is one way to cut down on waste from diapers.	中国小孩一般穿开裆裤，需要方便时往往随地就能解决。在当下的中国，环境问题日益凸显，这样做或许可以减少尿布带来的污染。
