Two Chinese sisters have landed a dream trip to Buckingham Palace and the Peppa Pig World theme park in the United Kingdom, after their online appeal to meet the Queen enchanted the British ambassador to China as well as millions of social media users.

Five-year-old twins Mi Ai and Mi Ni, who live in Beijing, appeared in a video on Chinese social media platform Weibo last week, where they spoke of their love of British animation Peppa Pig and their desire to visit the royal residence.

"Hello grandmother Queen," Mi Ai said in the video, which has been viewed more than 19 million times. "I'm five-and-a-half years old. I can play the piano, I am learning to dance and I'm learning English from my mom."
