I have never seen my mother's sadness. Tell me about it.

Until now, their hearts are still full of countless concerns, caring about their wives, caring about their children, and caring about this family all the time ... It's just that they are no longer young, their backs are tired, and their eyes have lost their former glory ... When I was young, my parents looked forward to our growth. They look forward to our marriage when we grow up. Parents gave their youth to us ... now let them give their youth to us.
