What does it mean that old slaves hate books and don't change geese?

It is a misunderstanding of Mi Fei by people who don't know calligraphy and its history. These two kings have always been the research objects of Mi Fei, and Mi Fei has made a lot of comments on calligraphy, all in order to suppress the Tang Dynasty and the Jin Yang Dynasty. However, Mi Fei's statement that he cursed Wang Xizhi in his later years is not groundless, but many people who don't understand it are wrong.

When Mifei was in his thirties, he got Wang Xianzhi's December Post, which later became the Mid-Autumn Post. He is between Wang Xizhi and Wang Xianzhi, and prefers Wang Xianzhi's frankness and naturalness. He thinks he is very angry with Wang Xianzhi. I think the reason for doing this is to break the blockade of Xihe River and explore a new style of writing. Mi Fei has always been a person who likes to bring forth the old and bring forth the new, and likes to show his personality, not only in calligraphy, but also everywhere in life, so he is called Mi Dian. To borrow today's slogan, Miffy doesn't take the usual road.
