Abstract: Due to the turbulence in the Wei and Jin Dynasty, belief crisis occured in Confucianism. Some scholars started to deepen their probe in the meaning of life, directing the Wei and Jin Thought to metaphysics. Such a period was historically known as "Awakening Time". Under the influence of the view, people claimed personality, stinked to pursue simplisity and naturalness in art verve. Such kind of taste can be obviously detected in calligraphy at that time as well as in' some theories on calligraphy. This paper is intended to research on the source of View of Naturalness reflected in the form and review of calligraphy.
