What songs did you often listen to when you were a child, and you didn't understand what he meant until you grew up?

Only my mother is good in the world. This is the first song I learned. At that time, no matter where I went, my grandparents were proud to let me sing to others. At that time, I only knew that if I sang, they would be happy and happy. At that time, I really didn't understand the meaning of the lyrics.

I didn't really understand until I grew up that only mothers are good in the world, and children with mothers are like babies.
