Can I hang calligraphy and painting behind my desk?

Sure, you can hang up. I just don't believe in superstition. Calligraphy, oil painting, Chinese painting, etc. Can be hung on the back of the office desk and chair, and you can choose what you like to hang according to your personal wishes. But the content of the work should be carefully considered. Calligraphy is enlightening and can show a person's taste and connotation. It is a good office decoration.
