 The Character Pai Mei is based on Pak Mei, the originator of the  "White Eyebrow" kung fu technique. According to legend, Pak Mei was  one of the few masters left following the decimation of the Buddhist  temples, and later sold out other masters to save himself and his  team during an attack they had mounted that subsequently went wrong.  For this reason, Pak Mei Kung Fu has always been known as the  "forbidden technique," and Pak Mei himself has been a villainous  figure in Chinese folklore and film for hundreds of years.
