State run media: Some, but not all the media is state-run. State run media generally gives a more unbiased view regarding to what’s happening. Other private own media sometimes publish news without fully investigating the event, or intentionally over exaggerate the situation for viewership. So state run media is actually relied upon by many people.
Different opinions: quite a few, as long as it’s not against the fundamentals of the government. AFAIK people in many cities protested against biochemical factories to be built in their cities, and most of them succeeded. As for policies directly from the government, China is now encouraging couples to have more than 1 child, which is not very welcomed on the internet. I have seen quite a lot of people criticizing that policy. Shanghai now also has the strictest wast sorting rules in the country as a trial run. Many people complained it, but it’s still there. The government pays attention to the people’s opinions and they sometimes adjust their policies based on the opinions.
Censorship: heavy. From the smallest things such as no blood in games, no cigarettes in TV shows, no pornography or anything related to sex in any art forms (books, videos, paintings, etc.) to larger ones such as limited access to the global network, or the Great FireWall as you might know. The general reason for doing so is ‘to protect the children from bad influences’, which on a certain degree makes sense. But this kind of ‘one size fits all’ policy is not what we like, but it’s there. There are signs of reform, but it takes time. This part might sounds weird to you, but I actually think the firewall is good for the country. For those who don’t know how to get a VPN or who don’t want to get a VPN, getting outside information does then no help. Probably all they care about is eat shit and die. For those who use VPN for porn only they don’t care either. For other people who use VPN to gather information and learn about the world, they are ready to accept different opinions and think critically, so most of them are able to tell valuable information from biased opinions.
So overall, the government wants stability and unification, so they can develop the country as well as maintain their regime. The people also understand that in order to develop the country, it has to be stable. Massive riots aren’t uncommon in Chinese history, and none of them helped the country to thrive. Most Chinese people know there’re still a lot of problems in this country, but they have faith in this government.
