Zuckerberg and his girlfriend Priscilla Chan stayed in the Apple store on Nanjing East Road for nearly 10 minutes trying out its products, but they didn't make an appointment in advance, according to store workers.

Zuckerberg visited China in 2010 and met with the heads of several Chinese Internet companies, including Baidu Inc, Sina Corp and Alibaba Corp.

In a report, Facebook said that its monthly active users around the globe reached 845 million, but it has not entered the Chinese market.

Zuckerberg，with an estimated net worth of $17.5 billion, ranks 36th on Forbes 2012 world's billionair list.
