We all know of how West Poison Au Yeung Fung's deadly snake venom was transferred onto Wong Yung's soft body armor by Nam Hei Yan (i.e. Gong Nam Freak # 4), and how this later became Yeung Hong's undoing.
Did Wong Yung *ever* scrub that poison off of her armor, or did the poison remain on the armor all the way through ROCH and for the rest of its existence as far as we know?
