Chinese citizens have to tow the line. The company I worked for had operations there, when our guys meet with counterparts then and ask probing questions everyone clams up, and one off to the side says we can't talk about bad things.
If you go against it you have reprogramming training classes.
We even have Chinese police stations here in Canada and they go knocking on doors because a Chinese citizen has said something negative about the homeland. And coerce them into going back to the mainland. This is not me reading it on the web, this is coworkers at the house when it happens to their room mates.
Stop trying to make China a utopia it is not. I agree with Socialism, but not a dictatorship.
It woukd seem you are being paid to promote China propaganda, or you are severely deluded to what goes on there.
A survey of citizens that know they cannot speak ll without retribution to them or their family, will always look positive. Please use some critical thinking here.
