What do girls mean when they say that boys have sharp chins?

With the rapid development of society, people's aesthetics are also changing rapidly. It is increasingly believed that if a boy's chin is pointed or his face is long, his face will look better. But from the perspective of feng shui, I don't think it's a good thing for a man to have a sharp chin. It means that they are narrow-minded, narrow-minded and have no flexible qualities, but they do not involve vitriol.
