Compared with Han Dynasty and Western Jin Dynasty, Wang Xizhi's calligraphy style is characterized by exquisite brushwork and changeable structure. Wang Xizhi's greatest achievement is to increase and destroy the ancient law and turn the simple calligraphy style of Han and Wei dynasties into exquisite and beautiful calligraphy style. In a word, the introduction of Chinese character writing from practicality to the realm of paying attention to techniques and tastes is the awakening of calligraphy art, which indicates that calligraphers not only discover the beauty of calligraphy, but also can show it. Few later calligraphers have not copied Wang Xizhi's calligraphy posts, so they have the reputation of "book saints". His regular script, such as Le Yi Lun, Huang Ting Jing and Dong Fangshuo Hua Zan, was quite famous in the Southern Dynasties, leaving various legends, and some even became painting themes. His cursive script is honored as "the sage of grass" by the world. There is no original trace in the world, and there are many calligraphy books, such as Seventeen Sticks, Le Li Yi in Small Letters, Huang Tingjing and so on.
