Qin Gui's calligraphy is very good. He writes neatly and steadily, and is good at seal script. Tao once saw the calligraphy "Jade Rabbit Spring" on the pillar of the Confucian Temple in Jinling, calling it "very impressive". Qin Gui's calligraphy has been handed down all over the world, such as poem notes and deep heart notes, and Qin Gui's ink is also included in Zeng Hongfu's Notes on Maple Trees in the Southern Song Dynasty.
According to folklore, Qin Gui invented Song-style characters, but there is no conclusive historical data to support it. According to Lu Xixing's research, Songti characters only came into being and became popular during the years of Zheng De and Jiajing. Although the characters in Qin Gui's works are exquisite, they have nothing to do with the appearance of Song-style characters.
