Calligraphy seals include name seals, leisure seals and corner seals.

1. Famous seals generally have red inscriptions on one side and white inscriptions on the other. Or engrave the surname on one side and the first name on the other to use both together. The size of the seal is roughly equal to or smaller than the inscription. The seal can be placed around the signature. The distance between the two square seals should not be too far or too crowded, and should be approximately equal to the position of one or two seals.

2. Pressed corner seal. Used in the lower left or right corner of the painting. The corner seals are larger than the name seals and are mostly square or rectangular, regardless of the red and white inscriptions. The content is collectively called leisure chapter, which can be aphorisms or aphorisms.

3. Introduce the first chapter. Most are rectangular, but some are oval or irregular. It is used on the right side of the first two or three characters of the title, so it is called the lead. The content is similar to the corner seal.
