Su Shi Ceng Yun: "As for poetry, as for literature, as for Han's retreat, as for painting Wu Daozi, as for books, as for beauty, the changes of ancient and modern times can do everything in the world." Yan Zhenqing, born in Linyi (now Linyi, Shandong), was an outstanding calligrapher in the Tang Dynasty. I used to be a plain satrap, called Yan Pingyuan. During the Anshi Rebellion, Yan made great contributions to the fight against thieves. When he entered Beijing, he was an official minister, a prince and the founding father of the county, so he was also called Yan. When Li Xilie rebelled for generations, Prime Minister Qilu "bit hate" instigated the emperor to ask Zhenqing to surrender. He was unyielding and was killed by Li Xilie. He is honest, clean and honest, has a sense of justice, never condescends to the powerful, condescends to flatter, and is famous for his benevolence and righteousness.
Yan Zhenqing is a descendant of Langya family with profound family background. Yan Zhitui, the fifth ancestor, was a famous scholar in the Southern and Northern Dynasties. He worked in Liang, Beiqi, Beizhou and Sui, and wrote family instructions for Yan. When Yan Zhenqing was young, his family was poor and lacked paper and pens, so he used a pen to brush loess water to practice calligraphy on the wall. Chu Suiliang was a beginner, and later learned Zhang Xu's brushwork. He also absorbed the characteristics of the four schools in the early Tang Dynasty and accepted the brushwork of Zhuanli and the Northern Wei Dynasty. He completed the vigorous and broad creation of colorful regular script, which set a model for regular script in Tang Dynasty.
His regular script is contrary to the calligraphy style of the early Tang Dynasty, featuring brushwork. It is a typical example of perfect combination of calligraphy beauty and personality beauty. His calligraphy style is called "Yan Ti", which is also called "Yan Liu" with Liu Gongquan, and has the reputation of "Yan Liu Jin Gu".
