Just before Gwok Jing was injured by West Poison Au Yeung Fung and Yeung Hong, he had gone with Wong Yung, Chow Bak Tung, and North Beggar Hung 7 Gung to steal delicacies from the kitchen of the Sung imperial palace in Lin-an. When the injured Gwok Jing returned to Kuk Ling Fung's abandoned inn to be healed by Wong Yung, Hung 7 Gung wasn't with them, and the old beggar would not reunite with his students for quite some time afterward.
Where did Hung 7 Gung go during that time? Did he really stay in the imperial kitchen and eat for months? Wasn't he worried about what happened to Gwok Jing and Wong Yung?
