Cai Wen, a fan of Shu Dao, is good at running script and attacking official script. He draws lessons from the past and is eclectic. Look at his delicate and graceful works, without losing strength and changing rules. In his understanding of epigraphy, he solved the problem of cutting the front, and finally formed his rich, neat and meaningful calligraphy style and composition, which won high recognition from authoritative figures in contemporary calligraphy circles.
