During DGSD, Ah Chu and Kiu Fung disguised themselves, respectively, as Beggar's Union Elder Bak Sai Geng and an anonymous low-level Beggar's Union member to shake down Madame Ma for the true identity of the "Leader Big Brother" who had caused Kiu Fung so much grief. Although ultimately, Madame Ma gave them a false lead (Prince Deun Jing Tsun of Dali Kingdom), Ah Chu actually came pretty close to guessing the true identity. In fact, when Madame Ma first began hinting at whom Leader Big Brother was, she said that this person had great authority in wulin, and could mobilize vast numbers of people. Ah Chu's *first* guess, indeed, was Shaolin Abbot Yeun Chi (who indeed, as was later revealed, the real Leader Big Brother).

Tragically, Ah Chu didn't know that she had guessed correctly on the first try, and believed Madame Ma's lie instead.
