As one of the new members of the advisory board of Tsinghua University business school, he attended a meetup with Tsinghua students yesterday evening. Speaking Chinese through the whole event, Zuckerberg explained why he has learned the language:His wife is Chinese. Last month Facebook hired twenty Chinese students who will begin work for the company next year, he said. Facebook and Zuckerberg have been well received by Chinese media, commercial circles and well-informed Chinese users (having a Chinese wife is definitely a plus!). Given Facebook is still inaccessible in mainland China, the company’s current strategy is to have Chinese companies with an international presence buy advertising on Facebook.
