Wang Xizhi (303-36 1), a Han nationality with few words, was originally from Linyi (now Shandong) and later moved to Yin Shan (now Shaoxing, Zhejiang). He was a general of the Right Army and a great calligrapher in the Eastern Jin Dynasty. He was honored as a "book saint" by later generations. His son Wang Xianzhi's handwriting is also very good. People call them "Two Kings", and another son, Wang Ningzhi, is a general of the right army, and is called "Wang Youjun" and "Wang Huiji". Representative works include: Le Yi Lun in regular script, Huang Ting Jing, Seventeen Guas in cursive script, Gua for Aunt in Running Script, Gua for Quick Snow Clear, Gua for Mourning, Preface to Lanting in Running Script, etc. Intensive study of body posture, imitation of heart and pursuit of hand, learning from others' strengths, and casting in one furnace created a running script of "natural, rich in gods and the world", which was praised as "the sage of books" by later generations.
