I want to write calligraphy for others. I write vertical edition. Should I write "xxx Village" under my signature?

Generally, a painting and calligraphy work with the other person's name is called the "last paragraph". As the name implies, it is generally written in the upper right of the text, xxx people will save, xxx will correct, xxx will correct, xxx will save, and so on. If you want to write them next to the last paragraph, it is usually above your own name. Of course, there are also cases where the "last paragraph" is added after the finished work.
