Can calligraphy works be signed in the middle or on the right?

Few people seem to sign in the middle, but if you are unconventional, you might as well try. I don't advocate it. By the way, did you create it yourself? If so, maybe you can try. I dare not anyway. This kind of typesetting really destroys the aesthetic feeling. As for the inscription on the right, it is really rare. It's just a matter of unaccustomed. The habits of our ancestors are still worth following.
