Is this sarcasm? While no authoritarian government can exist with no consent of the government, the PRC has no legal vehicle for citizens to disagree with the state.
that’s basically true, but it does seem china does have some nominal democracy at local levels, which then in turn elect upper levels and so on [1] so, while indirect, there does seem some nominal way to disagree as you say [1] https://en.wikipedia.org/wiki/Elections_in_China
While there are local elections, there's usually no right to stand for elections. These so-called elections, generally has only 1 candidate, or a few that are all communist members, with pretty much the same views. "Elections" where people can't stand to be elected freely are not elections, they are just some elaborate ceremony to rubber-stamp government official appointments.
