Alkuperäinen teksti - Kiinan kirjakieli / Wényánwén - 勝人者有力　自勝者強 u pitanju je stih, staro kineski...

Hey P, can you make me a bridge here or I need to find out who understand Literary Chinese?
Thx!

勝人者有力　自勝者強
Literally, it is maybe:
He who overcomes others has strength; he who overcomes himself is strong. (But I cannot figure out the difference between "have strength" and "be strong".)

Actually, it can also be:
He who overcomes others is potent; he who overcomes himself is omnipotent.

Thank you P, I'll do my best
