I watched in France a kung-fu movie in the early 80's (I believe) of which I do not remember much except one specific scene. The movie was part of the trend "a more or less random guy is taught kung-fu and becomes a better person" (the 1984 Karate Kid kind, and similar ones).
The scene I remember from this one is that the hero (a grown man, I do not remember if he was Asian or American) learns kung-fu (or a derivative) in an Asian monastery and the final test consists of him holding a red hot bowl (about 80 cm wide) in (or rather on) his forearms (not hands). He must transport the bowl over a few meters, during that time some signs on the bowl are burned into his forearms (I think he chooses the ones he wants when grabbing the bowl).
He can then open the exit door of the monastery and falls in the snow in pain from the burns.
This is in the first part of the movie, I think the real adventure starts from there.
I am aware that this is just one scene from a movies like there were many, but it was quite significant (it stayed in my memory for all these years) and the fact that the movie was broadcasted on French TV suggests that it must have been at least quite well known.
