Based on discussion about whether “Feeling at ease” can be regarded as criterion of Confucian ethical practice, this paper took the text of “three-year-mourning” of Yanghuo in The Analects of Confucius as a basis to demonstrate through text analysis, ethical analysis of “Feeling at ease” and ethical consideration beyond “Feeling at ease” from the perspective of “doing it with feeling at ease”. The research results show that Confucius proposes “doing it with feeling at ease” in discussion of “three-year-mourning” between Confucius and one of his followers called Zaiwo, whether "feeling at ease" can be regarded as standard of ethical behavior depends on whether conscience can be regarded as standard of ethical behavior; conscience has its subjectivity and objective restriction, and behavioral value judged by conscience is not consistent with its objective value. Confucius’s emphasis on ethical education lies in the ability to feel and express emotions properly and correctly, and then behavioral value judged by conscience can be consistent with its objective value. It can be seen that “Feeling at ease” can be used as preliminary criteria of Confucian ethical practice, but it is not the final criteria or the sole criteria. So it still needs to try to meet objective ethics moral standard and endeavor to cultivate “right conscience”.
