Stroke of Death (1979)
One-eyed Master: Tomorrow I'll be taken to the execution site.
Wei Chung: Really? The execution will take place?
One-eyed Master: Fear not. This will happen sooner or later. I will give you something now.

One-eyed Master: There's only half a piece of wood here. After you get out of jail, you must find the other half.
Wei Chung: The other half?
One-eyed Master: Yes. Put the two pieces together and you'll understand.
