What's your favorite painting and calligraphy? What do you like about it?

My favorite is probably Wang Xizhi's "A Thousand Miles of Rivers and Mountains" in Song Dynasty. "A Thousand Miles of Rivers and Mountains" is one of the top ten famous paintings handed down by China. It uses a lot of mineral pigments. After a long time, as long as you open the picture scroll, the paint will fall off, destroying the original appearance of the painting. Because of the fragile picture, this national treasure has been hidden in the Forbidden City for more than 20 years and has not been seen by the public. 20 13 the sixth issue of "the collection and exhibition of the forbidden city" was held in wuyingdian painting and calligraphy museum. In 2009, "A Thousand Miles of Rivers and Mountains" had a short exhibition, but it was not the whole volume.
