This article introduces the legal proposition put forward by Dong Zhongshu in the Han Dynasty, which emphasizes that the monarch should govern the country with virtue rather than relying on punishment. Dong Zhongshu believed that the rule of virtue and punishment correspond to yin and yang respectively. Virtue governs life, while punishment governs death. Heaven values the rule of virtue over punishment. This viewpoint promoted the integration of morality and politics in the Han Dynasty.
