Zhu Cheng Neo-Confucianism, also known as "Zhu Cheng Daoism", is one of the main schools of Neo-Confucianism in the Song and Ming Dynasties, and it also has the greatest influence on later generations. The natural principle of Neo-Confucianism is moral theology, which at the same time becomes the legal basis of Confucian theocracy and kingship. It was founded by Cheng Hao and Cheng Yi brothers in Henan (now Luoyang, Henan) in the Northern Song Dynasty, and spread to Luo Congyan and Dong Li by disciple Shi Yang, and finally reached its climax in the Southern Song Dynasty.
