Why did the calligraphy of the Yuan Dynasty abandon the book of Song Dynasty, but "follow the rules of Jin Dynasty and follow the distance of Tang Dynasty"?

The idea of the ruler.

The rulers of the Yuan Dynasty advocated restoring ancient ways. After calligraphy respected the ancient times, the patriarchal clan system in Jin and Tang Dynasties was different from the idea of pursuing originality in Song Dynasty.

The general situation of calligraphy in the early Yuan Dynasty was advocating retro. Zhang Kui Pavilion was built in Li Chu Tian, a literate scholar, and was dedicated to secretly playing with antiques. Yuan Wenzong has always been very lucky. Kuizhangge appreciates famous calligraphy and painting, and calligraphy once flourished. Zhao Mengfu, Xian Yushu and other famous artists are the representatives of calligraphy in this period.
