well not so uncommon, there are plenty of posts everywhere before it's taken down. If you use wechat the amount of 'read before deletion' are just a major category of gossips. I sometimes wonder do people outside of China really know the chinese 'domestic' circle well or am I so out of touch now? Also imho people don't tend to go 'against' the highest level government since it's very abstract. It's the everyday stuff that people care, which means local authorities that almost never get involved in any internationally focused affairs.
