The third Wudang hero who was crippled at the beginning of HSDS. He matched palms with Ah San at the beginning, and was no worse (although Ah San's strength is in techniques, not palm strikes). He then had the better of a tussle against a young Yin Yewang. He was also the disciple that Zhang Sanfeng most trusted to complete his missions, for whatever reason. So how good was he really?
