Historically, Su Shi, Cai Xiang, Huang Tingjian and Mi Fei were collectively called "Song Sijia". As a famous historical figure, there are many stories about Mi Fei.
Mi Fei studied calligraphy hard all his life, and his greatest achievement was running script. Although paintings have not spread to the world, many calligraphy works still exist. Most of the famous replies since the Southern Song Dynasty are engraved with their calligraphy books, which spread widely and have far-reaching influence. They are second to none among the "Four Great Calligraphers of Northern Song Dynasty".
Kang Youwei once said: "Tang Yan structure, Song Shang is interesting." Calligraphers in the Song Dynasty emphasized interest and individuality, especially Mi Fei, who was an outstanding representative of the four masters in the Northern Song Dynasty. Mi Fei studied books and claimed to "collect ancient Chinese characters". Although some people think this is a laughing stock, others praise that "Tian character block needs no praise, and the ancient Chinese character set can finally stand on its own feet".
This explains the success of Mi calligraphy to some extent. According to Mi Fei's self-report, before learning the Book of Jin from Su Dongpo, we can see that he was most influenced by five Tang people: Yan Zhenqing, Chu Suiliang, Duan.
