Why don't boys cry? There are no tears in the South China Sea. This sentence means that boys should not fall down easily when they have tears, that is, boys can't cry, because men are indomitable men, and then they can't cry, bleed and sweat, cry, be poor, move, be rich and strong, and be unyielding. What they say is that men do something and don't. Why can't boys cry? Is to have their own dignity, to have their own backbone, but there is another saying, that is, only when you have tears do you know that the sad place is a boy, and you can cry if you want to. Even if you encounter something particularly sad, the boy can't help it, but he will still cry.
