Copy someone else's font, calligraphy, signature xxx book, whose name is written?

For example, I want to write a calligraphy work now. The content is Lin Zexu's famous saying "Standing on the wall without desire is just right". How should I sign?

Gengyin year x month (i.e. next month, winter month, etc. ) XXX (that is, name) book. If you want to write longer, you can add the book to XX (location) at the end. If you want to write a little longer, you can write: Lin Qingze Xu sentence Geng Yin year X month (that is, next month, winter month, etc. ) XXX (that is, the name) book is in XX (that is, the location)
