The two top skills of the Beggar's Union Chief are the Hong Lung 18 Palms and the Dog Beating Stick Technique. Both skills are elite wulin skills, and the practitioners of such skills have often been top-level martial arts adepts (i.e. Kiu Fung, North Beggar Hung 7 Gung, Gwok Jing, Wong Yung).
Is there any way, however, for a person who knows both of these skills to use them *together*? Hong Lung 18 Palms is predominantly a two-handed martial art, leaving no free hand to use the Dog Beating Stick Technique at the same time. Thus, even if a person trained in the Hong Lung 18 Palms and the Dog Beating Stick Technique learned the Left/Right Hand Technique of Chow Bak Tung, that person still would not be able to use the two skills together.
The only time and way that the skills can be used simultaneously is if two separate people learn them, as Gwok Jing and Wong Yung did, then use the skills together against a common enemy. Short of that, however, is there a way a single person can use both skills at the same time?
