In particular, Wang Xizhi's "Quick Snow Clear Post", Wang Xianzhi's "Mid-Autumn Post" and Wang Yuan's "Yuan Bo Post" are deeply affectionate, so they ordered that the place where the law posts were hidden be designated as "Sanxi Hall" and the "Sanxi Hall" plaque was hung in calligraphy in class. Preserved to this day.
