Zhu Xi’s concept of legal execution was influenced by the traditional concept of Confucianism, but in view of the arbitrariness and imprudence of the Song Dynasty officials and the excessive looseness of the judicial system, Zhu Xi criticized the popular concepts of “karma” and “sympathy”. Having reflected on the reality of justice, Zhu Xi proposed his own “strict-oriented” concept of law enforcement, which calls for limiting the redemption, using penalties carefully and emphasizing the Confucian-Ethics and other measures relating. However, Zhu Xi’s practice of law enforcement are characterized as going beyond the law, protecting the weak, convicting subjectively. In practice, the “strict-oriented” concept doesn’t mean completely abiding by the law, but promoting the implementation of the Confucian values. Zhu Xi’s “strict-oriented” concept and practice of law enforcement is instructive for the construction and introspection of reasonable legislation, judicial justice, proper punishment and effective governance of China in nowadays.
