That's a way to fool children. In my hometown, there is a saying called "Be a big official when you grow up". That is to say, you have two spirals on your head, and they are far apart, so you can roll an egg in the middle, so that the child can sit on a big official when he grows up. In fact, this is groundless. Under normal circumstances, children with single rotation have smoother hair lines and better shaved heads, and children are less likely to cry because of shaved heads; For children with double curls, the hairline is not smooth, especially between the two curls. Shaving their hair is more difficult and painful. Children cry at the mention of shaving. Adults cajole children with "double-rotation". Over time, there is a saying that the future is measured by spin. To say good-looking, I think the single spin is good, the hair lines are smooth, and the hairstyle is of course good-looking.
