Liu Gongquan was a famous calligrapher in the late Tang Dynasty, who was good at regular script. His calligraphy is powerful, and the center of the structure gathers and extends around. Later generations called Yan (Zhenqing) Liu "Yan Gu". There are many inscriptions by Liu Gongquan, among which Xuanta Monument is the most famous and the most influential one in regular script.
Liu Ti's brushwork is clear and vigorous, with rigorous structure, open and generous expression and clean style. If simplified to fine print, Kang Youwei said, "It's extremely charming." Liu's big characters are refreshing, gratifying and more exciting. There are many imitators in modern times.
