道家思想：起源、核心概念及代表人物 - 老子与庄子

道家思想是先秦时期一个重要的哲学流派，以老子和庄子为代表。道家的核心思想体现在《道德经》中。'道'是宇宙万物的本源和主宰，外物都是从'道'演化而来的。而'德'则是'道'的体现。

The Taoist school of thought is an important philosophical tradition that emerged during the pre-Qin period, represented by Laozi and Zhuangzi. The core concept of Taoism is embodied in the Tao Te Ching. 'Tao' is the origin and ruler of the universe and all things, and everything in the external world evolves from the Tao. 'De' is the manifestation of the Tao.
