According to the bylaws of the Beggar's Union, the Union Chief MUST learn the Dog Beating Stick Technique and customarily also should learn the Hong Lung 18 Palms as well. This tradition certainly seemed to stick at least until North Beggar Hung 7 Gung passed on the Chief position to Wong Yung, who did not learn the Hong Lung 18 Palms because as a woman, she was not physiologically nor temperamentally well-suited to the Hong Lung 18 Palms.
Did her successor, Lo Yau Gerk, learn any of the Hong Lung 18 Palms during ROCH? If he also failed to learn it, then that's two consecutive generations of Beggar's Union Chiefs that didn't learn the Hong Lung 18 Palms.
