Some people say "When I was young， Laughter is a mood. When I grow up, Laughter is an expression."

Who said that? Who said that...

I was really happy when I was young, It's not bad when I grow up.

You are not in the mood to see my shipment,

That laughter, gongs, drums, and firecrackers.

Definitely a mood, Instead of an expression.
