Is the pinky finger the middle finger in china?

No. China has their own cussWords. There is no such thing as the "f Word" in China. You could walk up to everyone with your pink finger up, and nobody would care. They would just think you're a person walking around with their pinky finger up.

Still don't believe me? Fly there yourself and see.

So the answer, after all this discussion, is that there is NO such thing as " the pinky finger is the middle finger".
