Signing a contract is generally "modern style of literature and art" and "lively style of literature and art" The characters are Oracle Bone Inscriptions, Da Xiao Zhuan, and the signatures are in seal script, kai script and running script; If the text is official script, regular script or regular script, the signature can be regular script or running script; Cursive script is generally not used for inscriptions, except cursive script itself, because it is difficult to identify. Running script is the most widely used one, which is easy to identify and lively. The size of the paragraph should be smaller than the size of the text font, so as to make the priority clear.
The above signature forms are vertical works. For banner's works, generally only the contribution fee is paid, not the contribution fee. Like vertical works, the beginning and end of the inscription cannot reach or exceed the upper and lower words of the text of the work.
