In some sense,the mainstream values of Chinese philosophy largely base on the core concept of Tian and some of its related ideas,such as Tian Dao,Tian Ren He Yi,and so on. This paper aims to analyze the concept of Tian in early Chinese culture with respect to its natural,ethical,and love-embracing features,together with human efforts at acknowledging and exploring it. Meanwhile,the revival and reconstruction of the Doctrine of Tian Ren He Yi since the Han Dynasty are explained using three concepts —— Tianren Tongdao,Tianren Tongde,and Tianren Tonggou —— so as to illustrate the modern value of Tian Ren He Yi. The writer also clarifies the feasibility and indispensability of the construction of ecological views in Chinese philosophy by emphasizing two concepts,Buwangwei and Youzuowei,which demonstrate its typical ecological wisdom.
