Abstract: Liji (The Book of Rites) elaborates on the Confucian wisdom of the unity between natural way and social order. In Liji, daily life and political life are founded on and then justified and authorized by the ultimate natural order in all things under heaven. Knowing the world and knowing human are united in connecting nature, life and politics. Therefore, we should take consideration of and show respect for the dimension of nature in human activities so as to achieve the harmony between human behavior and natural order.
