Newsflash, you can find people in any country who don't like their government, and you'll obviously see these people over represented in the population that left the country. The fallacy of your argument is to conclude that the people you know hold the opinion of the majority of people in China. I made plenty of friends who from China in university, and most of them went back after graduating. Vast majority of people in China support their government and are proud of their country. Even western polling admits this.
You used so many words to tell us that you don't know anything about Chinese political system and expose yourself as being confidently wrong. Maybe spend some time educating yourself instead of flaunting your ignorance in public.
If you thought that was "so many words" reality is too complicated for you.
"The Government of the People's Republic of China is a unitary Marxist–Leninist one-party authoritarian political system under the Chinese Communist Party (CCP)."
The people who actually live in China consider their democracy to work far better than pretty much any western shithole country that calls itself a democracy and have consistently higher satisfaction with their government because unlike in the west they see it working in their interest.
Thinking that the number of parties is a measure of democracy demonstrates an infantile understanding of the concept. Democracy is a government that works in the interest of the majority and is held accountable by the majority. Procedural democracies such as seen in the west demonstrably produce terrible results in practice. As a recent study of US shows, the system does not actually work in a democratic fashion
