Fang Heng is a famous calligrapher in China, and his calligraphy belongs to one of the four Han Li. His existing calligraphy masterpiece "Fang Heng Monument" is of great historical value. The font of this tablet is simple and simple, and it wins by being clumsy. The shelf is solid and heavy, like a crouching tiger shoveling. The strokes are straight and thick, and the pen is like a stone. It is angular and horrible. The rules and regulations are full of words, and the fairness is oblique. Calligraphy is broad, round and magnificent, and the Han tablet is unparalleled, which is rare in the history of calligraphy. The protege Zhu Deng and others carved stones to praise the work. At the end of the inscription, there are two small lines: "Disciple was born in Leling Plain, Zhudeng, and the word is West Shu." Weng Fanggang thought Zhu Deng was a calligrapher. This tablet has been recorded frequently since Ouyang Xiu in Song Dynasty, and it is one of the famous Han tablets. The inscription on the tablet is wide and thick. Gu Zhuo and Fiona Fang are both elegant and magnificent. As far as rules and regulations are concerned, the lines are full of secrets, which is different from Chen Shi and Cao Quan. The inscription on the tablet is written in Yang Wen's official script, which has a special charm, neat structure, rounded strokes, seemingly tall and straight, and high spirits. Weng Fanggang in Qing Dynasty said: "The inscriptions are wide and dense, but there is not much room for them. It seems that after Yan opened the official book, it gradually disappeared. ..... Gage's book is also between the two monuments in Jing Jun and Zheng Gu. " (Hanshu Jinshi Lu) The inscription in Hua Yao's Tang Fu Manuscript in the Qing Dynasty said: "Jing Jun is ancient, but it is very strict. If the change in Fang Heng is unfair, it will be from strict steepness. " He Ji Shao called it "ancient stubbornness". This monument has a great influence on future generations. Yang Shoujing said that the Fang Heng Monument is "ancient and developed, from which many books have been published". Yan Zhenqing's popularity can also be seen from his calligraphy in the Tang Dynasty. In the middle and late Qing Dynasty, Han Li and the North Monument were advocated, and the calligraphy style changed greatly. Yi Bingshou, a famous calligrapher, learned his essence from Fang Heng.
