Actually yes, you can walk around Shanghai with ugly words about the government. As far as I know there are no laws against it. There are laws against plotting to overthrow the gov or causing civil unrest similar to the ones that exist in the U.S. or UK. I just fact checked this with my Chinese wife. She has a degree in Chinese Law. Could someone use your t-shirt to concoct a case against you relative to these laws? Maybe. But the Chinese police have bigger things to worry about. I have heard about people in the U.S. being tossed off airplanes and detained due to the content of their t-shirts. The Chinese Internet has massive amounts of chatter expressing anger at the government. Some of it gets removed by the gov and site management. But not all of it. There is plenty of juicy stuff to read online.
