Facebook co-founder, CEO Zuckerberg thrills Chinese students with 30 minutes of Mandarin

China may ban Facebook, but not its co-founder Mark Zuckerberg, and he entertained an audience of students with a 30-minute chat in his recently learned Mandarin Chinese at a prestigious Beijing university.

There was no explicit discussion of the ban or any Facebook effort to enter the China market during Wednesday's question-and-answer session at Tsinghua University.

But Facebook CEO Zuckerberg noted during his talk that the social media giant already helps some Chinese companies gain customers abroad. He cited computer maker Lenovo's ads on Facebook in India.

Zuckerberg married Chinese-American Priscilla Chan in 2012 and said he was learning Chinese.

His pronunciation was far from fluent, but he maintained the conversation for a half hour and the students responded with warm cheers for his effort and laughter at his humor.
