What is JJ Lin's personality?

This is silly. When I was a child, I lost a bet with someone and actually squatted on the ground like a big brother next door. I'm very talented. I heard that he still has a hobby of writing poems. His music is very good, and he cares about young people very much. For example, Kym, for example, has a good relationship with his disciples. Adu is polite and has no airs.
