At the beginning of ROCH, I believe it was mentioned that former Gong Nam 7 Freaks Leader Ohr Jen Ngok had old relations with the family of Luk Lap Ding. What was the nature and extent of this relationship? I know that Gong Nam's *other* Luk Family (that of Luk Sing Fung and Luk Gwoon Ying, which was unrelated to the Luk family of Luk Lap Ding) once hired Ohr Jen Ngok and his elder brother to help pursue Mui Chiu Fung and Chan Yeun Fung, but Luk Lap Ding's family was not involved with that at all.
