If you are asked to be a commentator on the forest of steles and introduce calligraphers' works, help immediately. . . . . . . . . . I need it now.

Liu Gongquan (778 -865), whose real name is Cheng Xuan, was born in Jingzhao, Tang Dynasty. He was a prince, who was called "Liu" in the world. Because he was also named Duke of Hedong by the emperor, later generations also called him "Liu Hedong". He is a descendant of Yan Zhenqing, and later called them "Yan Liu", which became a model of calligraphy in past dynasties. Together with Zhao Mengfu, Yan Zhenqing and Ou Yangxun, they are also called "Four Great Calligraphers".

Liu Gongquan, 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 an official life, grew up in the Forbidden City and had a successful career. Emperor Wenzong called his words "Zhong Wang resurrected, but it is hard to see with a pen": Emperor Mu Zongdi asked him how to use a pen best, and he said, "Use a pen in your heart, and your heart is right." 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".

Liu Gongquan wrote many books and erected many monuments in his life. Here, introduce some of his masterpieces:

1. Engraved Diamond Sutra (in 824, at the age of 47) Liu Gongquan's official book was carved as a horizontal stone, 12 blocks * * * each line 1 1 word. The original stone was destroyed in the Song Dynasty. The only Tang rubbings were found in Dunhuang Grottoes and are now in the Paris Museum. This is an early masterpiece (or cloud, which was written by Liu Gongquan, a student of Dunhuang Mogao Grottoes, but belongs to Liu Ti). His brushwork is meticulous, thin, vigorous and charming; The structure is meticulous, taking the shape of longitudinal length, tight in the middle palace, spreading in all directions, and pulling it out with clear strength. "Six Valley" can be known here, and so can Liu Jizhong's books. Jiyun said, "The Diamond Sutra says that there are Ling (tomb), Wang (tomb), Ou (tomb of Yang Jian), Yu (southern China), Chu (tomb of Sui Liang) and Lu (tomb of Cambodia). Today's test of his book is a must, especially valuable. " (Postscript of Guang Chuan)

2. Li Sheng Monument (829, aged 52) is located in Gaoling County, Shaanxi Province. The monument is 10 ft 4 in. high and 5 ft 8 in. wide, with 34 lines of 6 1 words. Pei Du wrote, Liu Gongquan wrote, and sealed the forehead. This monument was already full of flowers and stones in the Ming Dynasty. Sun Qing Chengze's Summer of Gengzi said: "Although the words are peeling off, they look tall and straight at first glance, but they are still available." Compared with the Diamond Sutra, it strengthens the concepts of firmness, angularity, pointedness, straightness and straightness. But in some places, the words seem stiff and cramped.
