Ask for a famous calligraphy sentence written for my father!

I think there are at least three places to pay attention to:

1. Calligraphy usually writes ancient poems (modern calligraphy works, which I personally think are funny), but ancient people don't write articles and poems to their elders except congratulations (except commemorative ones), so what you can write is basically limited to congratulations.

Father's Day is different from father's birthday, so don't write anything about birthday celebration.

Congratulations should reflect your father's identity, not exceed it. Only your father or your father's elders can say such things as an old horse crouching tiger.

That's about it.
