There was a quarrel between two people. One day, zhang SAN said 3 * 8 = 24, and li si said 3 * 8 = 21. The county magistrate listened and said, "drag zhang SAN out and hit twenty boards! "Zhang SAN dissatisfied:" clearly is he stupid, why hit me?" County official answer: "with the person that thinks 3*8 = 21 can argue for a day, still say you not stupid? Who won't you hit?" The story tells us, don't compete with people who don't understand, because you may end up hurting! Compete with the same good people, don't compete with the stupid, time will give the best proof, and be yourself.
