: At the end of the Warring States Period, Ying Zheng first came into power and Lu Buwei had just been exiled. Although the Qin State was strong, the people's livelihood was still poor. The people had no soft food to eat, no high chairs to sit on, and farming efficiency was low. This is an era that is about to unify the six countries, but is full of primitive wildness.
