Despite their difference in age (15-20 years?), Gei Hiu Fu and Chow Chi Yerk belonged to the same (fourth) generation of Ngor Mei Sect disciples. Both shared quite a few things in common: Gei and Chow each was, for a time, Mit Jeut See Tai's chosen successor to become the fourth leader of the Ngor Mei Sect. Both also fell for men from the hated Ming Cult.
But did the two martial sisters ever really meet each other or train at Ngor Mei Sect at the same time? By the time Chow Chi Yerk arrived at Mt. Ngor Mei, the incident between Gei Hiu Fu and Yeung Siu had already occurred a number of years earlier, but I'm not sure if Gei's predicament had been discovered by Mit Jeut See Tai yet. Was there ever a time when Gei Hiu Fu and Chow Chi Yerk were at Ngor Mei Sect together, or was Gei effectively gone by the time Chow joined?
