Ma Xiangang is a man capable of something not many others are or would have a practical reason to be -- he can touch live wires filled with scrotum-popcorning electricity and feel no pain whatsoever.
As with most superpower discoveries, Xiangang found his by acting like a braying jackass. One day when his television quit working, he went to go monkey with the fuse box to try to get it to come back on, accidentally touching a live wire in the process. Normally this story would end with people standing around a pine box and telling their favorite Ma Xiangang stories, but instead of white hot electric death, Xiangang felt nothing at all. Rather than praise his good fortune and call an electrician, he decided to touch the wires again. You know, just to check.
"I figured I'd either die or get superpowers. It was pretty much 50-50."
Even more amazing is that even when touching live wires with hundreds of volts coursing through them (enough to put a horse on its ass), he feels no pain at all. In fact, Xiangang claims it makes him feel energetic, which is almost certainly him just screwing with us. We're also pretty sure he's lying when he claims he can give diathermic massages (deep tissue massages done with an electromagnet) using only his hands.
