Which Tang dynasty calligrapher is known as “Crazy Zhang” for his wild cursive style? The answer is Zhang Xu.
Zhang Xu was an eighth-century Tang calligrapher and poet from Suzhou. His explosive, energetic cursive earned him the nickname Zhang Dian, commonly translated as “Crazy Zhang” or “Mad Zhang.” Stories say that wine and intense excitement helped release the spontaneous brushwork for which he became famous.
Legend also credits him with learning from movement: one account connects his understanding of cursive rhythm to watching a sword dance by Lady Gongsun, while another describes observing a chaotic confrontation involving porters. These stories emphasize the physical energy behind his writing, even though they are traditional anecdotes rather than securely documented biography.
Zhang Xu was not limited to wild cursive; he was also skilled in regular script and wrote poetry. He is often paired with Huaisu, nicknamed the “Drunk Su,” in the phrase “Crazy Zhang and Drunk Su,” identifying the two as the great cursive masters of the Tang era.
