China is a democracy.

Yes, the Republic of China appears to be a democracy.

About the People’s Republic of China, we can read in Wikipedia:

A movement for increased democracy and liberalization stalled after the Tiananmen Square protests and massacre in 1989.

So, we read that democracy never came.

China is a unitary one-party socialist republic led by the CCP.

So, we read that only one party is allowed to exist and rule. We also read about CCP propaganda, which I think you have consumed too much:

The PRC officially terms itself as a democracy, using terms such as “socialist consultative democracy”,[186] and “whole-process people’s democracy”.[187] However, the country is commonly described as an authoritarian one-party state and a dictatorship,[188][189] with among the heaviest restrictions worldwide in many areas, most notably against freedom of the press, freedom of assembly, free formation of social organizations, freedom of religion and free access to the Internet.[190]

I should note that according to its own words, the People’s Democratic Republic of Korea (North Korea) is also a “democracy”, even if its passing of power among the Kim family resembles a hereditary monarchy. If you take words and slogans at their face value, you’ll be easily mislead.

P.S.
