During the turbulent times of the Warring States Period, Chen Mo, a commoner in Qinjian, traveled through the kingdoms of Wei, Qi, Qin, Chu, and Zhao, witnessed the contention of a hundred schools of thought, and recorded the path of seeking the path in troubled times from a commoner's perspective. The key to governing the world lies in "taking the law as the bone, benevolence as the flesh, Tao as the soul, and using both as the function." The four are in harmony with each other to stabilize the people internally and subjugate the foreign barbarians externally. The people of Li "enjoy their work and live in peace", and the princes "enjoy their virtues and fear their majesty". This is the cause of long-term stability and peace in the world.
