Yes, I live in China. I am Chinese.

but I can't really imagine how that must be in China...

I have no idea about how to make it (censorship) clear.
Try to imagine if you were a sheepherder. Your sheep can walk around everywhere (but) within your hedges. They can eat, drink, leap, whisper, play together.... everything is fine, normal, OK, right? And even your neighbor thought your are a nice guy. But...
You can shear your sheep anytime you want/needed. You can kill your sheep when they tried to bite you. Or maybe there is a lucky sheep, all in all she will be another meat on the store.

I guess this thread will be deleted eventually. Because this is a forum talking about software, but not a politics forum. Right? People always saying like this.  :-\ ;D

ur welcome
