Mark Zuckerberg has shown off his language skills before, but now he's gone an impressive step further, offering business advice to students in a 20-minute speech in Mandarin at Beijing's Tsinghua University this week.

Zuckerberg posted the video, which has already been viewed more than 1 million times, on his Facebook page on Saturday. During his remarks, he highlighted three key pieces of business advice: Stay true to your vision, care more than anyone else and fight to stay relevant and ahead of the game.

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! Posted by Mark Zuckerberg on Saturday, October 24, 2015

Knowing when to stay the course is vital, he suggested. Zuckerberg told a story about how 10% of Facebook users threatened to quit the service after the company introduced News Feed in 2006 — a feature that shows users the activity of their friends. "Today, that would be like 150 million people telling us they were going to quit," he said.

"We care about what people think. But we also know that connecting people is important," he explained. "Most companies would be afraid of losing so many people, so they would take the easy path and give in ... We knew News Feed was important for our mission, so we stayed strong."

At the time, Zuckerberg posted an open letter apologizing for failing to simultaneously introduce proper privacy controls when launching the new service.

Zuckerberg said he sees similar stories of fortitude in the success of Chinese companies such as Alibaba and Xiaomi.

When advising students to remember that the more you learn, the more you find needs to be done, he even quoted Alibaba founder and Chinese business leader Jack Ma: "Compared to 15 years ago we're big. Compared to 15 years from now, we're still a baby."

The Facebook founder is on the board of Tsinghua's School of Economics and Management and has impressed audiences there before, taking part in a 100% Mandarin question-and-answer session in 2014.
