As a Manchu ruler, why did he choose Wang Xizhi's calligraphy in the process of carrying out cultural policies?

His calligraphy is very representative.

First of all, his calligraphy is extraordinary and he has a profound calligraphy culture education, which is one of the reasons for his free and easy atmosphere and chic behavior.

I think Wang Xizhi's position today is inseparable from his contribution to the history of calligraphy.
