Liu Gongquan (778-865), the last great calligrapher in the Tang Dynasty, was born in Yaoxian County, Shaanxi Province. He inherited the calligraphy structure of his predecessors and created the so-called "six-body", which was a model for later generations until he entered the printing age. His calligraphy incarnates thousands and spreads among the people and even abroad. His calligraphy was always valued in Tang Muzong, Jing Zong and Wenzong. He lived in the official residence, served books, grew up in the Forbidden City and had a successful career. Literati called his ci "Zhong Wang's resurrection is hard to see". Mu Zongdi asked him how to use a pen best. He said, "With a pen in your heart, your heart is regular." This famous saying was passed down by later generations as a story of "pen admonition" "Liu Ti" is as famous as "Yan Ti", also known as "Yan Liu Jin Gu".

Zhang Xu, Yan Zhenqing and Huai Su were in the prosperous Tang Dynasty. There were Liu Gongquan and Shen Chuanshi in the middle and late Tang Dynasty. Liu Gongquan took the banner of regular script from Yan Zhenqing and created his own "Liu Style", reaching another peak. Later generations called it "Yan Liu", which became a model of calligraphy in past dynasties.
