"Insect book" is a variant of seal script, also called bird book, bird seal script, bird insect book and so on. Named after the font looks like a worm. "snail body" is an artistic font, which is decorated with winding strokes on the basis of the structure of seal script.
During the Spring and Autumn Period and the Warring States Period from the 6th century BC to the 2nd century AD, the use of worm books reached its peak, usually appearing on the flags, weapons and bronzes of various vassal states. Because the strokes of "Worm Book" are complex and changeable, it is also difficult to imitate, so it was also used by the ancients to write documents and play an anti-counterfeiting role. However, "worm book" is not conducive to cultural communication, and "totem" has a stronger meaning.

In a word, the idiom "small skill of carving insects" is a derogatory term, and it can also be used to be modest, and is often used with "insignificant".
