From what I have seen, the views of most people in the US about conditions in China are 20-50 years out of date.
China was, perhaps, most Orwellian under Mao. From the Great Leap Forward, to the Cultural Revolution, the ideology from the top really did oppress and dehumanize people at all levels.
That said, the economy after Deng has opened up considerably. It is now acceptable to have a profit making business that is privately owned. The supermarkets are well stocked and people usually have the money to shop in them. The cities are vibrant and people have freedom of movement for vacations, etc. In ways that never existed before, the needs of the average person are being met in today's Chinese society.
The problem, of course, is the political system. It is horribly oppressive to anyone who questions the power of the Communist Party. But, frankly, the vast majority of people feel like they can ignore most political questions as being of only limited relevance for their day to day life. Like people in the US, they are concerned about jobs and making ends meet and taking care of family, etc. And, there *are* jobs. They can freely move between jobs (although not between locations, which is a very different matter). They don't have the 'sport' of complaining about their leaders. But, in the US, these complaints are usually just sport and have little actual consequence.
And, of course, this is mostly true of those in the cities and in the favored areas in the East. The current treatment of the Uighurs shows what can happen outside of those favored areas. There is also a LOT of unofficial racism against anyone not ethnically Han. This shows itself in a variety of ways like promotions and finding jobs or apartments. Of course, the US has a similar issue for its own ethnic minorities.
When I was there, the main concerns of younger people seemed to be whether they would be able to get an apartment. it seems that all of the good ones are now in the hands of the older generation, so the younger people have to wait for a relative to die before they can afford to get their own place to stay. They are also interested in whether they will be allowed to have two children.
I think there will be problems ahead, though. Those who are making money in business will eventually want more political power. That will produce a showdown between the government and businesses. And, while the government seems to have a lot of goodwill because it has allowed things to open up economically, that goodwill may easily transfer to the business leaders that actually produce the goods. How the government will react to that challenge is the big question in my mind for the next couple of decades.
In terms of the OP, it is clear that China dealt with this pandemic with a lot of force, closing down in ways that would not be tolerated in the US or Europe. But they also succeeded. Even if their numbers are cooked, they ended up doing better, by far, than the US response. And they could do so because of their authoritarian system and the fact that people were willing to follow the directions of the government.
