Is Gu Naiping's calligraphy and painting valuable for collection?

Nowadays, celebrity calligraphy and painting are either vicious or antique, and I think the rest is unnecessary. Why do you say that? Because now the cultural level of ordinary people has improved. An old man practicing calligraphy on the road with a mop can write good calligraphy. As for painting, there are many people who can turn a painting into a digital photo. What does it mean to collect a lesser-known artist? Besides, this whole book of two kings' words is hung on the wall. When you introduce it to others, you say, Oh, this is the original work of Wang Xizhi that I found. How domineering that is.
