The Chung-Yung was written by Tzu-ssu, the grandson of Confucius, to put on record the teachings of Confucius on the nature and conduct of life. These teachings did not spring from Confucius. They had already stood the test for more than 2000 years, when he devoted his life to the task of expounding and completing them. By putting them into writing, Tzu-ssu hoped that the wisdom of long ages of experience would be saved from loss, amid the hubbub aroused by new schools of thought and the chaotic state of the country.
