As Beggar's Union Chief, Kiu Fung must have known how to use the Dog Beating Stick Technique (it's a requirement for all Beggar's Union Chiefs), and knowing his talent, Kiu Fung almost certainly mastered this exquisite skill. Throughout DGSD, however, Jin Yong never depicted Kiu Fung using the Dog Beating Stick Technique.
Does anybody know the reason that Jin Yong never depicted Kiu Fung using this skill? One a few occasions, most notably when he fought over two-hundred enemy warriors at Tsui Yin Manor, Kiu Fung probably could have made good use of the Dog Beating Stick Technique, but he never exhibited it.
It's really a shame...a missed opportunity. In THE CONDOR HEROES TRILOGY, we saw how well characters such as North Beggar Hung 7 Gung, Wong Yung, and Yeung Gor used the Dog Beating Stick Technique, so it's a shame that we never get to see Kiu Fung use it.
