Mark Zuckerberg might be world-famous for being the CEO of online giant Facebook, but in this obscure Chinese documentary he and his new wife Priscilla Chan are mere cameos in the background. The documentary shows a 2-second clip of the couple out for a stroll in Shanghai earlier this year, just weeks before their recent wedding. It is a rare glimpse into the everyday life of this multi-millionare – hardly surprising that the clip went viral in China!
