Yan Zhenqing has opened up a brand-new realm of calligraphy: in terms of characteristics, Yan has a brand-new figure, strict statutes and great momentum. From the aesthetic point of view, the beauty of face and figure is dignified, masculine and artificial, and the beauty of number develops synchronously, which sets the rules for future generations. From the perspective of the times, the early Tang dynasty inherited the rest of the Jin and Song dynasties, but failed to stand on its own feet. As soon as Yan style appeared, the new style of Tang Doutan casting became one of the distinctive features of the prosperous 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".
Among them, "Guo Bei" and "Duo Baota Bei" are his masterpieces in the middle of the year, and his personal style has not yet formed, which is refined, beautiful and handsome. Yan Bei is the first masterpiece of the old man, and at this time, his vigorous and powerful personal style has been formed. The works in his later years are represented by Magu Mountain Xiantan, and his brushwork is more Gu Zhuo-like.
