Mark Zuckerberg speaks Chinese at Tsinghua University, Beijing   

"I just gave my first ever speech in Chinese at Tsinghua University in Beijing -- on why you need a strong sense of mission to change the world.

This was also my first real speech in any language sharing how I started thinking about Facebook's mission, what has kept me going through challenging times and what our mission means now looking ahead for our community of 1.5 billion people.

This video also has English subtitles and you may find it interesting if you're thinking about building something or are interested in Facebook's history.

The themes of believing in your mission, caring more deeply than anyone else and always looking ahead are relevant to anything you might build.

Last year I joined the board of Tsinghua's School of Economics and Management. This is a great center of innovation and many of the students here will become global leaders in technology, business and government. It's an honor to have the opportunity to help this university and talk with its students. I look forward to coming back again next year!"
