Gao Lian was a famous opera writer and a health care scientist in Ming Dynasty. He put forward the viewpoint of "keeping in good health and abstinence first" in "Three Knows". Although he thinks it is an instinctive pleasure for people to drown on red. But sex and life are together, and God and Qi are interdependent. If you indulge in it, it will inevitably affect the harmony between body and mind and hurt Yin and Yang. Gao Lian listed ten methods of abstaining from prostitution and prolonging life in the book "Yan nian zhi Wei Jian": "Yin and Yang are in harmony, and the connection is moderate; When you enter the room, you can forget the scene; Don't drown Xiao Ai, don't trap Qian Tong; Enchanting and greedy, the city makeup is not close; Cherish essence as gold, cherish body as treasure; Take medicine frequently to supplement the next yuan; Not greedy, not chaotic; Don't dream, don't lose your dreams; If you are less greedy, you can always know the commandments; Avoid color, such as hatred, abstinence. "

To sum up, Gao Lian elaborated on the concept of abstinence from the following aspects: the sexual life of yin and yang, the sexual skills of entering the house, the sexual psychology without delusion, the sexual health care of being diligent in taking drugs, and the excessive sexual morality, which enriched the content of China's sexology. It is worth pointing out that Gao Lian lived in the Ming Dynasty, when Neo-Confucianism prevailed. It takes courage and courage for him to abandon the hypocritical preaching of "murderous desire" and explore sex culture. At the same time, his abstinence theory inevitably left a limited relic of his time. In addition, Gao Lian put forward another aspect of abstinence in Notes on Life and Happiness, namely sexual taboo under special modality. Personnel taboo "advocates that all men and women should abstain from sex after being overjoyed, furious, feverish, unclean menstruation and drunk."
