Danba Monument, also known as Emperor Danba Monument, Zhao Mengfu left a lot of calligraphy traces for later generations in his life. Among the many works handed down from generation to generation, the works in his later years can best represent Zhao's calligraphy style, among which the classic works and behavior works are the best, and the Danba Monument written by him at the age of 63 is called "the ancient spirit is unparalleled, and the quality is the first". The whole post is done in one go, with pure stippling and no slack. Basically, the whole article is an open letter, and occasionally there is calligraphy. The upper and lower veins are connected and flow naturally, all of which are the positive veins of the "two kings". The structure of Li Beihai's book is solemn, mellow and elegant, and it is a pure state of freedom. Its opening part is basically pure block letters, and there is a small amount of cursive script at the end of the article, which shows the time flow of the whole creation from rules to freedom, and also plays a role in regulating the disadvantages of regular script. Perhaps it is because of the need to carve tablets and block letters, so it is not suitable to show the changes of black, thin, old and tender ink color.
