What's the difference between moire and moire? The question is, what's the relationship with ray?

Yun Leiwen is the original pattern of ceramic decoration, and the pattern is a spiral line of arc curling or square folding. Circular arc is also called moire, square fold is also called thunder, and Yun Leiwen is a general term for both.

Lei Wen has nothing to do with thunder itself, but with lightning, which is composed of straight broken lines. Lightning also gives the impression that people are disconnected. Lightning is also called lightning, so it has something to do with thunder.
