The first emperor in Chinese history to unify the six countries declared the entire unification of China at the same time. In fact, when Qin Shihuang destroyed the six kingdoms in 221 BC to complete the great cause of reunification, there was still a patriotism. The reason why the patriotism did not perish was that it was too weak and only occupied one city.
And for a long time depended on the State of Qin. It was not until 209 BC, when Qin II demoted the king of Weiguo to a commoner, Weiguo declared its demise.
