Qin, an era full of contradictions and charm. It has order under the iron-blooded law, but also has the ideological confinement of burning books and humiliating Confucians; it has the majestic spirit of the Great Wall, and it also has the tragic song of blood and tears of Meng Jiangnu crying at the Great Wall; it has an eternal foundation of books with the same text and cars with the same track, and also has the hardship of people's livelihood under the severe punishment and law. This is a pioneering era when an empire is born and everything is renewed. It is also a troubled time with turbulent undercurrents and dangers.
