In typical Andhra style boys who guard buffalos in villages, he is seen riding water buffalo in Vietnam!!! Instead of going to Vietnam, had he come to Andhra he could have enjoyed these rides more that too in beautiful scenic village side in Andhra as well enjoy unrestricted access to FaceBook.

FAceBook is not permitted  in Vietnam but it welcomed Facebook founder vacationing in the communist country. Zuckerberg and his girlfriend Priscilla Chan arrived in the Southeast Asian country on Dec. 22 on a two-week visa.

Vietnam Net reports, "[Zuckerberg] and his group of nine members spent a night on the Ha Long Bay, which has been recognized as one of the new natural wonders of the world. The Facebook's CEO rowed a kayak himself to make an excursion on the bay and then visited some caves of the bay."

Vietnamese website Tuoitre News reported that Zuckerberg, 27, and Chan have already spent about $6,000 on travelling by private helicopter.

The pair have been dating since Zuckerberg’s sophomore year at Harvard, where they met at a Friday night party for Jewish fraternity Alpha Epsilon Pi. Chan, a Chinese-American from the Boston suburbs. struck up a conversation with Zuckerberg while waiting in line for the bathroom.

“He was this nerdy guy who was just a little bit out there,” Chan told the New Yorker last year.

When Zuckerberg left Harvard in 2005 to focus on Facebook full time, he recruited classmates, including Chan, who, according to The Harvard Crimson newspaper, told him, “I’d love a job at facebook,” before offering him a Twizzler.

These days, Chan identifies Zuckerberg as her partner on her Facebook page and, according to tech writer Sarah Lacy, she has imposed a set of rules on her steady, including, “One date per week, a minimum of a hundred minutes of alone time, not in his apartment, and definitely not at Facebook.”

While the couple seem to be enjoying their vacation, it’s likely, given Zuckerberg’s insatiable work ethic, that he’s finding some time for business, namely expanding Facebook to Vietnam, where social media is growing. Though Facebook is blocked by the government’s censors, locals can still access the site with relative ease, but it seems they would rather choose local offering Zing Me.

Zuckerberg, whose net worth is measured in the billions, doesn’t need the money. Rather he seems motivated by his obsession to bring Facebook to one billion users worldwide.

There is no evidence that Zuckerberg is meeting with any Vietnamese officials while on vacation, but he did meet with web entrepreneur Nguyen Trong Khoa, who has been called the "tycoon of domain names" in Vietnam.

Facebook was co-founded by Zuckerberg in 2004. The world's biggest social network currently has 800 million active users.
