It mainly refers to the selection of inscription fonts, and the principles are "today is not more ancient" and "the more static it is". That is to say, if the later script is the text, the earlier script title is not needed; If the dynamic style of the book is the text, the static style of the book is not needed. Commonly used conventions: the text is Oracle bones, Zhong Ding, Xiao Zhuan, han li, and the inscription is made by Li, Xing, Kai and Xing Cao; If the text is in script, line and cursive script, it is appropriate to use running script and cursive script. In order to "live in style" and "live in style". Of course, the same style is not unusable, but it is monotonous. Block script, line script and cursive script can be used interchangeably, but block script is a cursive script, which is rather dull. The cursive script is inscribed, because the characters are difficult to read, and few people use it. In practice, the running script is suitable for all kinds of books, and its application is also the most common.
