A friend sent a photo with the signature of Dong Wang. Who knows if Dong Wang is a calligrapher? Is his calligraphy valuable?

There is a man named Dong Wang in the art encyclopedia. I don't know if it's him. It feels like a gift from a friend, and it's kept as a facade. If he likes it, that's good. Many people are calligraphers, and their words are worthless. This mainly depends on the final conclusion of future history. It's hard to say yet. He can keep it if he likes. If he doesn't like it, he can communicate with other people's works.
