Abstract: The two Chinese characters Dao (道) and Li (理) make the relations between the three different basic categories of principle (in Chinese, 道理, Daoli ),morals (道德, Daode) and ethics (伦理, Lunli) subtle and thought-provoking.Dao (道) and Li (理),put together,constitute the word Daoli,i.e "principle". Principle (道理) and morals (道德) share the character of Dao (道) while principle and ethics (伦理) share the character of Li (理). Morals and ethics each has its element from Principle,so the two categories are homogeneous and develop their own unique connotation and become two most fundamental and important categories in ethics.
