In the second episode of DIY: Chinese Inventors, we took a trip to Jilin, China to visit our friend Sun Jifa. Nearly a decade ago, Sun lost his hands in a fishing-related explosion. Sun couldn't afford prosthetic arms, but he didn't let this stop him from obtaining bionic hands—using his inventive imagination, Sun built his own prosthetic hands. Since then, he's used these hands to build over 800 metal hands for other men unable to afford the prosthetic devices recommended by doctors.
