Ideological and political rivals for centuries, Taoism, Confucianism, and Buddhism deeply influenced one another. For example, Wang Bi, one of the most influential philosophical commentators on Lao Tzu (and the "I Ching"), was a Confucian. The three rivals also share some similar values, with all three embracing a humanist philosophy emphasizing moral behaviour and human perfection. In time, most Chinese people identified to some extent with all three traditions simultaneously. This became institutionalized when aspects of the three schools were synthesized in the Neo-Confucian school.
