Poor money refers only to the author's name, nothing else. According to the position, it can be divided into the previous paragraph and the next paragraph. The first paragraph is written on the right side of the work, and the content is generally written as "the kindness and elegance of so-and-so" or "to Mr. so-and-so", while the next paragraph is written on the left side of the work, and the content is generally the author's name, writing time and place. Generally, a long signature should include the time, place, author's name and Zhai number. Whether writing one line or two lines, it should not be longer than the main content, but shorter than the main content, and at the same time, a certain space should be reserved for stamping.
The font used for signature is exquisite, generally later than the font used for text. For example, seal script can be signed with official script, but it cannot be signed with official script, regular script, cursive script or running script. Official script cannot be signed with regular script or running script, but regular script can be signed with official script. Generally, running script can be signed with any kind of characters, and running script is a common font. The way to make no mistakes is to use running script.
