Calligraphy and painting should be signed and sealed, and the seal should not be larger than the word. Of course, it is natural to stamp a big seal and a small seal. Chinese painting is stamped under the lettering, down to the bottom corner, and corner seal is not allowed. For example, the upper right corner and the lower left corner can be stamped with leisure stamps, and the upper left corner and the lower right corner can be stamped. If the above words are printed near the lower corner, there is no need to stamp the leisure stamp.

Don't leave stamps idle at both ends of Chinese painting and at the edges of two corners. Sign in the upper right corner, sign in the lower left corner and sign in the lower right corner. If you don't need to stamp here and force it, it will be self-defeating.

Extended data:

Name and type: usually placed under or around the author's name. Sashimi and tangyin are usually placed around or under the style, and are also used for greeting the head and the upper right corner. The seal cutting of gossip, auspicious words and epigrams is generally covered in the lower right corner of calligraphy and painting as a sign.

Collection and appreciation seals are generally covered in the blanks at the left and right bottom corners of calligraphy and painting, and can also be mounted on calligraphy and painting without destroying the blanks of calligraphy and painting itself. There is also a cover in the most conspicuous position of calligraphy and painting to show its authority.

Appreciation of calligraphy and painting is mainly observed from the aspects of style, pen and ink, color, composition, chapter, painting, seal cutting, paper, mounting, inscription and postscript, and mainly from the aspects of calligraphy and painting itself, calligraphy and seal cutting.
