For instance, the Qin people's costumes are in black and white, implying a totalitarian society where one has to abide by a unified code of conduct and thinking. Meanwhile, the Zhao people are in bright red, suggesting it is a brave and rash population.

In making this documentary, the director said he has raised many questions before the viewers: Why did Qin, a marginal state in the far west, eventually unify China? Why did the rule of morality and benevolence, a tradition that the rulers of the Yan State clung to for more than 800 years, not succeed? Why did the Wei State, the most powerful and fierce in the early stages of that historical moment, fail itself?
