How to write the shelf structure of calligraphy?

Therefore, to study the structure (also known as "knot character" and "shelf structure"), we must first understand the essence of calligraphy art; Calligraphy is a semi-abstract and semi-figurative line art. Not only is its stippling form an abstraction of all things in the world (including people's own images and actions), but its structure, that is, the composition principle, is also closely related to all things in the world. Generally speaking, the structure must conform to the principle of making every word vivid. In order to achieve this requirement, no matter what calligraphy genre or genre, it must meet the basic requirements of stability, symmetry and stippling. Only studying "internal connection" and "external connection" can only solve the requirements of "symmetry" and "balance" In order to make every word have vitality, the artistic principles such as "stippling echo", "interspersed avoidance" and "saving changes and adding decorations" are completely powerless.
