In DGSD, there was a character named Chiu Cheen Sheun, who famously remained enamored of his younger martial sister decades after she had married another man ("Grandpa" Tam).
Near the beginning of ROCH, when Gwok Jing, Wong Yung, and Ohr Jen Ngok encounter West Poison Au Yeung Fung for the first time since LOCH, Wong Yung attempts to further confuse Au Yeung Fung by responding to his question of "What's my name?" with "Your name is Chiu Cheen Sheun *Lee*."
Was this a reference to the DGSD character?
