I lived in China for many years. The society there is basically as free as the US.
I spent two weeks in China a few years ago. Very eye opening trip. There are many differences, but for starters:
1. The Internet is heavily censored. You cannot access FB in China (w/o a bad of tricks). Likewise, you are limited in what books & newspapers you can buy. Much of the TV fare is pure propaganda. {I found a series on heroic Chinese soldiers vs. Japanese occupiers in WWII to be a laugh riot]
2. Investments of Chinese citizens are restricted
3. You cannot just purchase a car. You have to take a number.
4. If you buy a house, your family can only keep it for 99 years.
5. Religious freedom is tenuous. While I didn’t experiences this directly (as I didn’t try to attend services on my trip), we had some Chinese visitors here subsequently (for about 4 months). One of their parting remarks about what they liked about America was: a) orderly traffic, b) clean air/good environment, c) open Internet, and d) ability to worship freely.
6. There are Communist Party representatives in most workplaces. [Some say that these are equivalent to our Federal Government inspectors, but I doubt it]
4. If you buy a house, your family can only keep it for 99 years.
