Calligraphy seals are generally divided into famous seals and leisure seals. Famous seals are generally signed after calligraphy works to show the author of the works.
Leisure chapters are more casual and rich in content, which can be words, images of elephants or other Buddhas to express the author's interest, and can also be used as an introduction or blank space. This "wealth and peace" belongs to this kind of seal.
There is also a collection stamp, which indicates that the work is XXX collection, and the general content is collection room's name.
