Explain the suzerain-vassal system in ancient China! Why is it not included in the territory of the People's Republic of China?

The succession of the king of a vassal state to the throne must be granted by the suzerain, who must pay tribute to the suzerain regularly, and the suzerain has the responsibility to help the suzerain maintain the ruling order. The main reason is that the suzerain has no sovereignty over the vassal state, and the invasion of modern imperialism forced the Qing court to abandon the suzerain and merge.
