Censorship

Here's a huge difference between America and China.

You must, must, must keep your mouth shut about any sort of China issue.
No matter how much anger and pain you a feeling about the country you just don't talk about it.
Because unlike America you can't freely speak about how much you "Hate your country".
There are different set of rules.
You get punished by the government if you do say things like that.
Or even taking pictures, that is not a tourist site, which is what I have been doing. Obviously I'm not going to stop taking pictures, but I could get in a lot of trouble.

But I cannot say anymore about it. So let's leave it at that.
