Yan Yu's previous theory of wonderful enlightenment can be traced back to Zhuangzi's Tian Zi Fang from the etymological point of view: "It is right to realize things without Tao." However, Zhuangzi's enlightenment made people realize that people should be purely natural, do nothing, and have little desire. It was after the spread of Buddhism in Wei, Jin, Southern and Northern Dynasties that enlightenment or wonderful enlightenment was really used to express aesthetic activities and understanding. For example, Xie Lingyun, a great poet in Liu and Song Dynasties, used enlightenment to express his aesthetic perception of natural observation: "Love is beautiful, and people who don't know the difference are worried about it." Tao Hongjing, the "Prime Minister in the Mountain" in the Qi and Liang Dynasties in the Southern Dynasties, discussed the calligraphy creation with Liang Wudi by enlightenment in On Books: "The name of this imperial edict is enough to make people realize." However, there are many sayings about Wu Miao, starting from the Sui and Tang Dynasties. The theory of wonderful enlightenment in this period was mainly aimed at calligraphy and painting that witnessed the existence of Taoism. The representative figures were Yu Shinan in Sui and Tang Dynasties, Sun, Li Simiao and Zhang Yanyuan in Tang Dynasty.
