Wang Xizhi's Preface to the Collection of Lanting is highly praised by calligraphers of all ages and is known as "the best running script in the world". Wang Jian is good at following the laws of Li, Cao, Kai and Xing, carefully studying the shape, imitating the shape with his heart, learning from others' strengths, preparing everything in one furnace, getting rid of the style of writing in Han and Wei Dynasties, and becoming a family of his own, which has far-reaching influence.
Legend has it that Wang Xizhi practiced calligraphy hard when he was a child. After a long time, the pool water used to clean the brush turned black. Later generations commented: "floating like a cloud, agile like a dragon", "the dragon leaps into the Tianmen, the tiger lies in the phoenix" and "it's natural, and the rich gods cover all generations". There are some idioms about Wang Xizhi, such as cleverness and quick marriage. The most obvious feature of Wang Xizhi's style of writing is exquisite brushwork and changeable structure.
Wang Xizhi's calligraphy has influenced bookstores from generation to generation. Ou Yangxun, Yu Shinan, Chu Suiliang, Xue Qi, Yan Zhenqing and Liu Gongquan in the Tang Dynasty, Yang Ningshi in the Five Dynasties, Su Shi, Huang Tingjian, Mi Fei and Cai Xiang in the Song Dynasty, Zhao Mengfu in the Yuan Dynasty and Dong Qichang in the Ming Dynasty were all impressed by Wang Xizhi, so they enjoyed the reputation of "book saints".
