Billionaires and royals are rushing to teach their kids Mandarin

The royal couple have two children and a third on the way. Their oldest son, Prince George, 4, began his first day of school at Thomas' Battersea in London. The school will teach Prince George Mandarin.

But he's not the only one who has picked up some Mandarin phrases. Prince William wished China a happy new year in Mandarin a few years ago.

Ivanka Trump and Jared Kushner have three children and hired a Mandarin-speaking nanny to help bring the language to their home.

Their oldest daughter Arabella, 5, displayed her language skills by singing the Chinese "Happy New Year" song in Mandarin earlier in 2017.

Facebook CEO Mark Zuckerberg picked up Mandarin a few years ago, and improved so much, he was able to do a 30-minute question and answer session in the language. His wife, Priscilla Chan, is the daughter of Chinese refugees who fled Vietnam. She speaks fluent Cantonese.

The couple have already introduced Mandarin into the house for their daughter Max. Zuckerberg uploaded a video on Facebook that showed his AI personal assistant teaching Max to speak Mandarin.

Amazon founder Jeff Bezos and his wife MacKenzie have four kids and have experimented with many different subjects to educate their children.

"We tried all sorts of things ... including off-season travel, kitchen-science experiments, chicken incubation, Mandarin lessons, the Singapore math program, and lots of clubs and sports with other neighborhood kids," MacKenzie told Vogue.
