I move the entry to Yau long - not sure about the other two credits but maybe hegrew up well and he is here?

Makes more sense that Cannibals (1972) belongs to Yau Lung 3

But Yau Lung (1) is definatly in it

Okay, I see now.

I checked ROAR IN THE WOODS and the kid could be Yau Lung, but I'm not sure. Strange is that the name Siu Yau ?? is listed in the HKFA and hkmdb cast list, but not in the movie opening credits. Maybe it is a mistake and no Siu Yau is in the movie. From the order in the credits I would guess Yan Yi (2) ?? is the kid in ROAR.
