Lai Zhide

Lai Zhide (1525 to 1604), also known as Lai Qitang, was a Neo-Confucian philosopher of the Ming period. He is credited with introducing into Chinese philosophy the well-known yin and yang symbol, the taijitu, a diagram of the great ultimate, of which the eleventh century Neo-Confucian Zhou Dunyi had also presented an earlier form. He wrote a commentary on the I Ching, the Explanation of the Classic of Change Annotated by Mr Lai, which was edited by Zheng Can in 1988. The Chinese Wikipedia article gives his years as 1526 to 1604, so the birth year is uncertain by one year.
