The hair on my son's back has formed a whirlpool. Is such a person's fate good?

It's nothing. It's a natural law based on personal physique. Don't scare yourself, it will go looking for trouble. If you pay special attention to it or keep it in your heart, it will actually cause you some pressure, make you think more and more, and make you more confused. Some children's hair forms a whirlpool, which is her physical problem or his problem.
