Mi Fei's pen-using characteristics are mainly good at forming elegant and extraordinary momentum and calm and happy style in the face, retrogression, turning and frustration. The beginning of the word is often quite heavy, and the middle is slightly light. When the side of the pen encounters a turning point, it will go straight down. There are also many changes in holding the pen. The focus of the next stroke is sometimes on the pen, sometimes on the pen, and sometimes in the middle of a stroke, a long horizontal painting has twists and turns. Hooks are also very distinctive.
There is always an inclination in Mi Fei's calligraphy. He wants to be left first and then right, and he wants to praise first and then suppress, all in order to increase the charm of ups and downs and the gas field of flying fast. After decades of rich collection of ancient Chinese characters, he is naive and natural, and never pretends. People who learn from Miffy will inevitably lose their "difficulties" even if they get the moon first in the water. Since the Song and Yuan Dynasties, there have been two attitudes towards Mi Fei's calligraphy: one is to praise but not to belittle, and to admire it to the utmost; One is that there are praises and denials, and most of them are praises. Those who hold the first attitude can be represented by Su Shi.
