It is said that children with cold hands and feet are not injured. I believe that?

How can a child with cold hands and feet not be loved? This is just a superstition, because everyone's physique is different in real life. Some people's hands and feet get cold easily, but that doesn't mean she says no one loves her, because some people do wear too much, and their hands and feet still get cold easily. It has nothing to do with his physique and love.
