In the US, I vote for a candidate that shares my views on important matters. I think you're in a Parliamentary nation, so you would vote for the party that shares your views. In either place, we can vote the party in power out of office. In China...
Maybe there is a non CCP person or party you can vote for in a particular election, but since there are no opposition parties, it doesn't matter. That giant legislature meets annually to hear reports and approve what Xi says to approve. You can't vote the CCP out, the Constitution says so. You can't vote to change the rules to something Xi disagrees with, the Constitution says so. The legislature can't pass a law that the CCP leadership does not approve of, the Constitution says so. The legislature appears to have control over who gets appointed to the higher offices, but in practice they are only ever given one option.
The military and police have more seats in their legislature than any non-CCP party. More than the top 4 combined. Let me repeat that in case you missed it, it's pretty damn important. THE MILITARY has almost 10% of the legislative seats! Non CCP parties combined have consistently held about 14% since the body was formed.
I know that where you live, neither the military nor the police hold ANY seats in parliament. The idea is absurd in the West, where the military is under civilian control.
It is a thin facade of democracy, and I don't know why you, an intelligent person, isn't seeing through it.
