Hi Calros,
You sir, are a genius! This helps me immensely! Gracious thanks
Additionally, I believe the last two names before "Ah Tak" are:
Ko Leung
Chan Kin Yat
Though I can't, obviously, translate their roles. However, my partner who speaks ten dialects including Mandarin translated Ko Leung's role as "Bath fighter" and Chan Kin Yat's role as "Massage customer". She was also able to give a Mandarin translation of "Chien Khun" for the name above Ko Leung. Hope that helps!
Many thanks again!
