Yang Guo is considered smarter than many people in the ROCH series (maybe except the Huang family), so can he be considered a true martial arts genius? He did create his own style of martial arts and mastered the dugu heavy sword after being taught by...a bird.
Another question: Would Yang Guo reach his maximum potential in the Dugu sword techniques if he had been taught personally by DuGu Qiu Bai?
