China fish scales and Japanese fish scales.

China fish scales are somewhat different from Japanese fish scales. Generally speaking, fish scales in China are relatively simple, while those in Japan are more complicated.

Fish scales in China are usually composed of several triangles of different sizes, arranged in a complex pattern. These laws include parallel lines, diagonal lines and intersecting lines. These lines form gaps of various shapes and sizes on the fish scales, thus forming fish scales.

On the contrary, Japanese fish scales are usually composed of many smaller and more complicated triangles, arranged according to more complicated rules. These laws include curves, S-shaped curves and so on, thus forming more complex and exquisite fish scales.

To sum up, China's fish scales pay more attention to the regularity and order of lines, while Japanese fish scales pay more attention to details and complexity.
