Primarily its important to keep in mind that the values of the Communist Party of China are significantly different than the generally known 'Communist Values', after the 60's they had to adjust and make changes.
With that said; I agree, and I always find it interesting how often the MC defies or overthrows the existing government in the novels. There are even depictions of corruption and authoritarian behavior is often called out as something the MC will struggle against.
I have noticed they are very careful when writing events around a government that is actually associated with 'real-life' China; if a government is of a Chinese nation (and not set in a historical setting), then its pretty rare for the government to be depicted in any negative light. (I'm open to counter-examples, just can't recall many)
Now that you point it out, it does seem that the novels that keep you immersed and interested in reading further have some sort of giant organization masterminding most of the challenges the MC faces.
