Shoujinti is a calligraphy font created by Song Huizong (Evonne, 1082~ 1 135), also known as Shoujinti or Shoujinti crane, which is a kind of regular script. In his early years, he studied under Xue Ji and Huang Tingjian, and joined the Chusuiliang schools. He was quite slim, beautiful and comprehensive, and changed his style from Xue Ji to Huang Tingjian, which was called "Thin Gold Body". It is characterized by being thin and straight, with a horizontal pen with a hook, a vertical pen with a point, throwing it like a dagger, holding it like a knife, and a slender vertical hook; Some couplets are like hairspring, close to calligraphy. His pen originated from Chu and Xue, and it was written in detail. The closing gesture was written in Huang Tingjian's big script, which was very imposing. "Imitation of Song Style" in modern art fonts is created by imitating the charm of Shoujin style.
