1. How is it possible that a world-class martial artist like Xiao Yuanshan didn't notice the killing of his entourage in front of him, even if he was in a good mood talking to his wife?
2. Xiao Yuanshan spoke Khitanese the whole time with the Central Plains attackers, which they couldn't understand. Did he really not know Han Chinese, even though his MA was taught by a Han Chinese? Also, you'd think such an important organized event would have at least one person who understands Khitanese from the Mainland side.
3. Given the unprovoked attack initiated by the Song people, how could Xiao Yuanshan neglect his wife and child to be killed easily? This doesn't make sense. He was an experienced martial artist by that time, he should instinctively know opponents would attack the weakest link first and protecting them should be his highest priority. This is after the Song people already killed his entourage. He should be on highest alert.
