China does not have a political system.

China's government is similar to the management structure of a business corporation. China's citizens are the shareholders of the state. All citizens are eligible to pursue a career either in government or the private sector. In either case, their career path progression - based on meritocracy - is similar. China's government operates like any of the top ten US companies.

There is no way for a citizen to come out of the blue like a Donald Trump or Kamala Harris to take over the helm of China's government by appealing to the masses.
