China's calligraphy is mostly written from right to left, mostly vertical lines, and few words are written from right to left. Therefore, many people like to write: "Record the contents of XXXX on the right", which is to explain the meaning of XXXX copied from the text on the right.
Of course, in order to adapt to the reading habits of modern people, there are also some works with few words written from left to right with inscriptions on the right; There is also a paragraph at the top and a signature at the bottom; Neither of these two signatures can be written as "right XXX", otherwise it will be ridiculous.
