Why does China ban dirty braids?

The reason why dirty braids can't appear in China;

1, mainly for fear of imitation by minors.

2. Dirty braid itself is not China culture, and there are some minorities.

3. China people are more traditional.

Dirty braid is a kind of hairstyle. Wrapping your hair tightly can not only prevent insects from growing on your head, but also be much cooler than a messy curly hair in summer.
