Facebook CEO Mark Zuckerberg went on a major charm offensive in China by giving a 30 minute interview where he answered everything in Mandarin Chinese. That was clever, for sure, but even more clever was posting a video of the interview to Facebook. The interview was at Tsinghua University in Beijing, where the university announced Mr. Zuckerberg was joining its School of Economics and Management Advisory Board. Again, clever. As noted by Wired, Facebook is banned in China—and boy, oh boy, did his Mandarin performance have this particular crowd wrapped around Mr. Zuckerberg's finger. Clearly he's taking a long view on entering the world's largest market, and this was a smart step in that campaign. Wired also noted that Mr. Zuckerberg learned Mandarin in 2010 as that year's self-improvement goal. I'd love for any Mandarin speakers to offer up their thoughts on his performance in the comments.
