Ng Yam-Chuen / (???) http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng , suspect he is

Unknown SB-Actor(34) / (??????(34)) http://hkmdb.com/db/people/view.mhtml?i ... y_set=big5, in

The 36th Chamber of Shaolin / ????? (1978) http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng

To confirm, we need a screen shot of "Prison Guard Fang Guan" in Heaven and Hell (1980)

Also, in 3th Chamber of Shaolin, Ma Koo (2) is credited but not Peter Chan Lung. Peter Chan plays a significant role just like Unknown actor (34). Suspect Ma Koo (2) is an alias of Peter Chan Lung.

Peter Chan Lung ... Abbot in charge of Staff Chamber/soldier (Ma Koo?)

Unknown SB-Actor(34) ... Abbot in charge of Sword Chamber (Ng Yam Chuen?)

There is no other significant role that can be associated with Ma Koo or Ng Yam Chuen.

Can anyone help?

I think a long time that Ng Yam-Chuen is Unknown SB-Actor(34) - but I always waited for a third movie with name and actor. But I must confess that the two big roles in 36 and HEAVEN are maybe enough evidence. What are other opinions?
