There is a point early in Kiss of the Dragon when the Chinese cop played by Jet Li is being searched for weapons. Around his wrist they find a band with a lot of little needles stuck into it. This doesn t indicate that he does tailoring in his spare time. These are acupuncture needles, and he can cure or kill with one deftly inserted point.
The title of the movie refers to the ultimate use of a needle, which he describes as highly illegal, as indeed it must be, altering the body s flow of blood so that it all rises to the head and bursts from every available orifice. I hate it when that happens. The Jet Li character is also master of the full array of the martial arts, and in this movie he needs them, since he is opposed by more or less every villain in Paris.
