In China's calligraphy, where are the horizontal axis and the seal?

Calligraphy, like Chinese painting, is a part of the composition of works. It is divided into the first chapter (leisure chapter) (which plays the role of echoing and completing the composition) and the famous chapter, and its position depends on the needs of the composition. However, there is a principle: the first chapter, as the name implies, is printed on the starting line (the position, size, shape and ink white should be determined according to the needs), and the famous seal is generally printed below the author's name (generally) at a distance from the name, and the size is slightly smaller than the size of the calligraphy work. Ps: Not the more copies, the better! In short, according to the needs of composition, avoid too much, miscellaneous and chaotic! !
