The full name of "General Yunhui Stele" is "Preface to the Shinto Stele given by General Yunhui Youwuwei to Qinzhou Governor Peng Guogong posthumously named Zhaogong Li Fujun in the Tang Dynasty". It is also called "Li Sixun Stele". The inscription records that Li Sixun was from the Tang Dynasty clan. In addition to the important events in his life as an official, Li Yong wrote a monument. It stands in the tomb of Li Sixun (653-718), the general of the Youwu Guard in the Tang Dynasty, in the Qiao Mausoleum of Pucheng, Shaanxi today. The year when the stele was built has not yet been determined, but it is known that it was after the eighth year of Kaiyuan (720) by Emperor Xuanzong of the Tang Dynasty. "Jin Shi Cui Bian" records: the height of the stele is one foot, one foot, three inches and six cents, and the width is four feet, eight inches and five cents. There are thirty lines of characters in total, with a full line of seven crosses. The text in the lower half of the stele is extremely incomplete.

  Li Yong is famous for his literary talent, especially for writing epitaphs. This stele is written in running script, which can be described as a change of stele. The calligraphy is thin and vigorous, awe-inspiring and powerful. The knots are long and fluent, and the ups and downs are moving and inspiring. It has always been regarded as the same as the "Lushan Temple Stele" People admire it. Yang Shen of the Ming Dynasty said in "Yang Sheng'an Collection": "Li Beihai's "Yunhui General Stele" is the first." Kang Youwei of the Qing Dynasty's "Guang Yi Zhou Shuang Ji" said: "If it is a Tang stele, it is Huairen's "Holy Teaching" "Preface" will not be discussed further. In addition, there are three steles that can be learned: "General Yunhui" by Li Beihai, which contains strange changes in rules; "General Pei" by Yan Pingyuan, which hides the method of division in Fenqi; "Mrs. Linghu's Epitaph" is full of twists and turns, and every gleam can be seen. It can be a good stone monument for students to learn running calligraphy, and it is also useful for writing."
