The movie is set several years after the An Lushan Rebellion floored the empire, and the capital city of Chang'an was on the edge of falling in battle.

这部电影的背景设定在安史之乱席卷全国几年之后，首都长安正处于战火边缘。

As a proportion of the population, more people were killed during the An Lushan rebellion in eighth-century China, for example, or by the Thirty Years War in 17th-century central Europe.

例如，8世纪中国的安禄山叛乱或17世纪中欧的三十年战争死亡人数占总人口的比例就比二战大。
