Countries change constitutions all the time, not sure why this is so significant. The point is that German constitution already allowed for this. Meanwhile, western style parliamentary democracy is just one implementation. If you think that's the only way democracy can work then you really need to educate yourself more. Having more parties doesn't make a country more democratic, the question is whose interests the parties represent. Chinese system is democratic centralism and it's clearly doing a hell of a lot better job representing the interests of the majority than any western system given that quality of life in China keeps improving while it's collapsing in the west. Claiming that Xi is essentially voting for himself is the height of comedy. The fact that you don't even know the basics of how political systems work really says everything I need to know. Bye.
