Self-consciousness is one of the major activities of maid. When Confucius and Mencius advocated "being benevolent is up to oneself" and "who else could do this if not me？," ways were shown to begin the search for self-consciousness. However, in the West and East Han Dynasies, through a long-term development of the concept "resonance between heaven and man," the law and the will of the "heaven" had become th source of unified and ultimate value system, and self-consciousness where the subject of value system rests on did not have chances to develop. Since the beginning of Wei-Jin Dynasties, so-called "literati's bearings" and "Wei-Jin styles" has been formed. Though seen in talks on absurdity and behaviors of willfulness, they clearly displayed the concept of self-consciousness. In the examination on the expression of self-consciousness, it is found that the common practice of "no yielding to others" and "to say oneself being the best" clearly changes traditional value system, from concentrating on morality such as modest, to emphasizing on personal talents. Yin Hao's bold claim of "I would rather be myself" manifested a direct connection between oneself and one's life, which reached the state of self-assurance. This reflects a profound aesthetic significance. The influence of self-consciousness on to the aesthetics in Wei-Jin period is two fold. First of all, the emphasis on creativity, personality, and one's carriage. Second, the stress on willfulness and being different. This new trend of self-awareness hence became prevalent among Wei-Jin literati.
