The NPC has a higher percentage of women than the US Congress (exceeding the world average).
Ethnic minorities make up 8% of China's overall population, but they make up 14.7% of the seats of the NPC. They also make up 7.3% of the more than 90 million members of the Communist Party of China (which also consists of 27.2% women). Ethnic minorities make up 39% of the overall population of the US, but only 25% of the US Congress.
A study by the Harvard Kennedy School found 93.1% satisfaction with the central government in China in 2016. US Congress currently has a 29.3% approval rating, but has been hovering below 20% for most of the last decade.
The two viable US political parties are overwhelmingly funded by billionaires and large corporations. Those two parties decide the criteria for acceptance into the presidential debates which prevents minority parties from gaining national prominence. Billionaires and large corporations also own all the major media outlets and platforms, and they use that power to control narratives and deplatform inconvenient political figures and ideas.
Therefore China is more democratic than the US. See how easy that is?
