Who knows what happened when Cao Cao met Ma Chao in Tongguan?

Turning defeat into victory, Ma Chao was forced to cut his robe and was rescued by his men. Later, Ma Chao and Han Sui joined hands, and Cao Cao (155-220) laughed. Ma Chao suspects Han Sui, and then Ma Chao wants to kill Han Sui. Han Sui had no choice but to vote for Cao Cao. Cao Cao and Han Sui were attacked from both sides, and Ma Chao was defeated, so he had to vote for Liu Zhang. Result: Cao Cao won and Ma Chao lost.
