The origin of Wang Sui's calligraphy in Song Dynasty is quite similar to that of Song Ke. Jie Jin's postscript "Sui Xue San Zhuan" said: "(Wang Song Sui) learned the cursive script of Kanglizi Mountain for the first time, and the printer Zhang You talked with Song, Wu Zhichun, Sun Zilin and Zhu Meng. When he saw Wei Gong, he asked the teacher to present the cursive script, and Li Si was the master of printing." After the court training, the "Examination of Provincial Characters" commented: "Strong and soft, beautiful and heroic, the rules are two kings, entering and leaving Xu Su."
