1, the signature of calligraphy works is very particular, and it depends on the font of your calligraphy content, which is not uniform. For example, if you write cursive script, if your signature is regular script, it is taboo; Writing regular script, you sign with seal script, is also the same taboo. What font is the best for the content, and try to use that font for the signature, which is more harmonious. Of course, the contents of regular script can also be signed with running script, seal script works can also be signed with regular script, and subordinate works can also be signed with cursive script and running script.
I hope my answer can help you.
