But you have to be smart to inherit the smarts I guess. His disciple (Su) and his grand-disciples seemed to have only a fraction of his smarts due to lack of ability. And its quite staggering that with such a fraction, they were head and shoulders better than the rest of the field (for Dr Xue at least).
HYS's maze seems to be in the same league as WYZ's chess trap IMHO.
HYS would have made a perfect XYP disciple. Smart, suave and a total weirdo. Too bad he was born too late.
