first, the extraction and derivation of "shape"
"shape" generally refers to the shape and structure of objects represented by graphics. China's traditional graphics are rooted in China's national and regional traditional artistic origins, and they are different from the modeling methods of modern graphics. China's traditional graphics mainly pay attention to the integrity and decoration of the real shape (or orthographic shape), and pay attention to the echo, comity and interpenetration between the shapes, and often follow the bone style of seeking integrity, symmetry and uniformity when constructing. For example, the most primitive and basic auspicious figure "Taiji pattern" in China, which consists of two fish-shaped patterns in black and white; The four dolls' "four happiness figures" can be seen on the top, bottom, left and right of the head, body, hands and feet of the two dolls (Figure 1); Nine squares and Mi Zige figures formed by the concepts of five elements and five parties, fish-shaped characters whose basic strokes are formed by fish-shaped features, and car-shaped characters whose basic strokes are formed by car-shaped features, etc.
