Wang Xizhi's calligraphy is good at all kinds of calligraphy, such as official script, cursive script, regular script and running script. He carefully studied the style, copied and imitated by hand, learned from others, prepared all kinds of calligraphy, and melted into one furnace. He got rid of the style of writing in Han and Wei dynasties and had a far-reaching influence. The style is peaceful and natural, the brushwork is euphemistic and subtle, and it is beautiful. The masterpiece Preface to Lanting is known as "the best running script in the world". His cursive script was listed as the standard of cursive script by later generations. In the history of calligraphy, he and his son Wang Xianzhi were called "two kings".
