Traditional classic calligraphy pays attention to respect for traditional classics, because calligraphy can also be divided into post school and monument school, so traditional classic calligraphy pays more attention to posts than monuments. They pay more attention to the techniques in traditional classic calligraphy, and have been trying to promote them, especially some classic calligraphy works. Therefore, this calligraphy school pays more attention to the skills and methods left by predecessors, and the calligraphy written is also more ancient.
Compared with the traditional school, modernist calligraphy pays less attention to classics, and they will pay attention to modernity, such as incorporating visual elements into calligraphy, which is commonly used in painting, but rare in traditional calligraphy. This is also an innovation of modernist calligraphy, which combines painting with calligraphy and gives calligraphy a somewhat abstract painting atmosphere. It pays little attention to the lines and rules in traditional calligraphy, but has a soft spot for spatial structure.
Postmodern calligraphy subverts the rules and regulations in traditional calligraphy. Because of absorbing the influence of western post-modern theory, subversive and non-subjective concepts are integrated into calligraphy, and at the same time, forms such as behavior art and concept art are added to calligraphy, which makes calligraphy more abstract and even ugly, but it also brings stronger visual impact.
