Calligraphy seal should be seal cutting seal, that is, seal should be seal script font.

Calligraphy seals are basically divided into three categories, namely, name seal, fasting seal and casual seal.

The name stamp is mostly four characters, that is, full name+seal (generally, the word "seal" is not used), such as "Qi Baishi seal" and "Zhang Daqian seal". If the name is only two words, it can be engraved as "X seal", "X private seal" and "X letter". You can also just carve two words, such as "Qigong".

Calligraphy seals, white and Zhu have no certain rules. Name stamps and name stamps are generally square, while leisure stamps are more casual, which can be square, rectangular and conformal.

Signature should be stamped with name stamp and name stamp. Leisure chapter is usually used as the first chapter, which is covered at the beginning of calligraphy works to echo famous chapters.

Calligraphy seals should not be covered more, and a work should not exceed three seals.

The principle of seal size is to use large chapters for big characters and small chapters for small characters. The seal is basically as big as the inscription.
