Zhao Mengfu claimed that the Biography of Ji An was a legacy of the Tang Dynasty, while Feng Yuan in the Qing Dynasty commented: "Although Jun Fang followed the European style and used his pen quickly, he still had to draw a book of praise and praise by himself." Ni Zan also said: "Zi Ang writes fine print, which is beautifully tied, and he hits hard with a pen. It' s really a shame for people in the Sui and Tang Dynasties. " (Quoted from Lin Shuzao's Sword), I am as good at writing as Zhi Yong and Yu Shinan, which is the highest in my life.

Zhao Mengfu's calligraphy works are characterized by quickness, elegance and beauty.

First, on the basis of inheriting traditional calligraphy, Zhao simplified the complex and turned the past into the present. His brushwork is neither vague nor mysterious, and the brushwork path of starting, transporting and collecting pens is very clear, which makes it easy for scholars to understand and follow.

Secondly, the appearance is round, the bones and muscles have connotation, its stippling is gorgeous and vigorous, the structure is broad and beautiful, and the stippling echoes closely. Soft outside and rigid inside, beautiful figure and strong skeleton. Scholars not only learn its shape, but also learn its spirit;

Third, the pen is square and square, and the lines are taken. When writing Zhao Ti, stippling needs to be round and colorful, but the structure of white cloth should pay great attention to being square and rigorous, horizontal and vertical, flat and stretched, and the center of gravity is stable. Only in this way can we grasp the characteristics of Zhao Ti. In addition, when he writes regular script, he uses running script slightly, which is one of the characteristics of Zhao Ti.
