Liu Gongquan (778 AD - 865 AD), courtesy name Chengxuan, was a famous calligrapher in the Tang Dynasty and a native of Jingzhao Huayuan (now Yaoxian County, Shaanxi Province). He rose to the rank of Prince's Shaoshi, and was known as "Liu Shaoshi" in the world. Liu Gongquan's calligraphy is famous for his regular script. He is as famous as Yan Zhenqing and is known as Yan Liu. He first learned calligraphy from Wang Xizhi. Later, he looked at the calligraphy of famous calligraphers in the Tang Dynasty. He thought that Yan Zhenqing and Ouyang Xun's calligraphy were the best, so he absorbed the strengths of Yan and Ou, and formed his own calligraphy between the Jin people's charm and Yan's calligraphy. Willow body is famous for its strong bones and is known as "Yan Jin Liu Gu" in later generations. He created many works in his life, mainly including "Inscription on the Bell Tower of the Huiyuan Temple of the Tang Dynasty", "Stone Carvings of the Diamond Sutra", "Mysterious Pagoda Stele", "Feng Su Stele" and "Shence Army Stele". There are also ink inscriptions "Mengzhao Tie" and "Wang Xianzhi's Pear Sending Postscript".

The culture of the Tang Dynasty was magnificent, and there were many famous calligraphy artists. In the early Tang Dynasty, there were Ou, Yu, Chu, and Xue; in the prosperous Tang Dynasty, there were Zhang Xu, Yan Zhenqing, and Huai Su; in the middle and late Tang Dynasty, there were Liu Gongquan and Shen Chuanshi. Liu Gongquan took over the banner of regular script from Yan Zhenqing, created his own "Liu style", and climbed to another peak. Later generations were collectively known as "Yan Liu" and became a model of calligraphy art in the past dynasties.

Liu's life, except for a short period of time when he served as an official abroad, was basically in the capital, in the palace, and by the emperor's side. Throughout his life, he has been constantly writing monuments for the royal family, ministers, and relatives and friends. Liu Gongquan is quite like a canary in a cage. Such a life makes him lack magnanimity, broad vision, and vast source of life. Yan's body has been changing from monument to monument, but Liu's body has changed less after it matured; Yan Zhenqing is like a roaring torrent, but Liu Gongquan is like cave water flowing in the deep mountains and old forests. These are two different sentiments of life.

In its heyday, Liu Ti achieved great success. In the mid-term, the charm of the setting sun. Late night, sunset in Liushu. The crown of Liu Gongquan's success is not only made of thorns of hard work, but also picked by standing on the shoulders of giants. He is good at absorbing the wisdom and achievements of calligraphy masters and turning them into his own calligraphy masters.

When he was young, he avoided arrogance and became famous. After he matured, he had noble character quality.
