This image of Kwan Yan from Young Lovers on Flying Wheels (1974) is wrong, he is the actor we tried to ID a while back if I'm not mistaken, not sure if he was ever IDed.

and this image from Duel of Fists (1971) also seems to be wrong

I guess the credits in the cast also might be false, so would be nice if someone could check that, will remove the ID from the images in a few days if no one objects.

You are right, both images show not Kwan Yan but an unidentified actor I call "Piggy". He is in many movies like "Mad World of Fools", "Inframan" and has maybe his most famous part in "Snake in the Eagle' s Shadow" as Chiang Kam's father. You can also delete Kwan Yan from the cast, if I remember it correct he is not at my cast lists for that movies (But I check the movies again and if he is in other roles in the movies I post that tomorrow).

This isn't Kwan Yan either in The Condemed, it's "Piggy"..

Deleted Kwan Yan also from the cast lists. I checked it: he is not in the 3 movies. Also removed wrong ID at "Delightful Forest" (was "Piggy" too).
