Shoujinti is a calligraphy font created by Song Huizong (Zhao Ji, 182~1135), also known as Shoujinti or Shoujinti, and also known as Shoujinti Crane, which is a kind of regular script. In his early years, he studied Xue Ji and Huang Tingjian, joined Chu Suiliang's various schools, and became quite thin, beautiful and comprehensive, and changed the second Xue (Xue Ji and Xue Yao) to form his own style, named "Thin Gold Body". It is characterized by being thin and straight, drawing the pen horizontally with a hook, drawing the pen vertically with a point, throwing it like a dagger, holding it like a knife, and the vertical hook is slender; Some couplet characters are like gossamer, which is close to calligraphy. His pen originated from Chu and Xue, and he wrote thinner. Huang Tingjian's large-character regular script is used in the closing gesture, which is very strong. "Imitating Song Style" in modern art fonts is created by imitating the charm of thin gold body.
