this part reeks of bs:
"TT: Will bagua quan help win fights?
HJH: Use the training methods in a fight and you will lose. But they will prepare you for a fight.
TT: Have you had a fight?
HJH: Not a real fight.
TT: So how do you know it works?
HJH: Our ancestors have already proved that.
TT: But suppose you did have a fight, wouldn't it prove something?
HJH: Any kind of proof is fake. If you find someone to fight, in the ring, for instance, it's not a real fight. It's not true. Fighting is actually about life and death."
Without experience fighting in the ring, or the street, it is hard to make an accurate value judgement on what a fight actually entails.
"TT: Have you had a fight?
HJH: Not a real fight.
TT: So how do you know it works?
HJH: Our ancestors have already proved that."
At least he's being honest. But I wouldn't go to learn from him. The last line I quoted really bugs me though, martial arts is fluid not some static religious law that was set down by some founder without room for change.
