In HSDS, Hu Qingniu (aka Green Buffalo) had trouble coming up with a cure for Zhang Wuji's Xuanming Divine Palm-induced injury. However in DGSD, Su Xinghe easily came up with a cure for the people injured by You Tanzhi's ice worm palm. Both palms were in the toxic yin family.
Do you think that Su Xinghe > Hu Qingniu in medical expertise?
