Dream comes true: Twins go to Buckingham

Mi Ni said she and her sister want to visit the gardens at Buckingham Palace, just like Peppa Pig and her friends did in a special episode that aired last May around the time of the royal wedding between Prince Harry and Meghan Markle.

In exchange for an audience with the monarch, the girls promised to help around the home, give their mother massages, and take their grandmother's slippers at the door whenever she visits.

British Ambassador to China Dame Barbara Woodward answered their call with her own video, inviting the twins to her residence in Beijing.

"Hello Mi Ni and Mi Ai," she said in a post that has been viewed over 9 million times. "I'm the British ambassador, so I'm the Queen's representative in China. I'd like you to come and visit me in my house in Beijing and we can perhaps have tea and scones in a British style."
