Neither Had The Other Convinced

"Who's jealous of you? If you hadn't resorted to underhanded tricks, would Yunmeng marry you?"

"Was that underhanded? I was competing fairly with you. You're the one who could not best me and yet you still blame me!"

The two old men were simply like kids. When it came to old scores, there would be no stopping their quarrel; they would argue over just about anything they could think of.

The two quarreled, their faces and ears red with anger. Everyone at the table exchanged looks, flabbergasted.

It looked like the last time, when the two old men shook hands and made peace, it had just been an act. In fact, neither of them had the other convinced.

Or it could be said that the two old men were born to be mortal enemies—don't even hope that they could get along with each other peacefully.
