The word 蟠 is composed of two parts: worm and fan. The original meaning of the word is to use a dustpan to remove the impurities of the rice through the up and down bumps, in this process, the rice with impurities will be rolled back and forth in the dustpan in order to separate the rice and impurities. Therefore, the word 匫 in the word 匀 means rolling.

The Evolution of The Character (Etymology)
When the tide worm is frightened, the body will be rolled into a round ball, which is why the tide worm is named a cockroach.

The tidal worm is a polypod with 7 pairs of slender breasts and limbs, and walks like a broom sweeping the floor. At the same time, the tide worm lives in a dark and damp place, and its living environment is similar to that of rats, so it is also called a rat woman.
In addition, when the yang rice is removed, the dustpan is bumped up and down to form an upward and downward rolling phenomenon. If the upswing is called positive, the lower volume is negative. Therefore, the rat woman is also known as the negative cockroach, the rat negative and so on.
The extension of the cockroach is related to the habits of the tide insects.
