Emma Raducanu is already one of the most impressive 18-year-olds you've probably come across.

The tennis star is the current British No. 1, the reigning US Open champion and has achieved a WTA (World Tennis Association) ranking of world No. 22 all before her 19th birthday.

She rapidly shot to fame after becoming the first British woman to win a Grand Slam singles title since Virginia Wade in the 1977 Wimbledon Championships, simultaneously becoming the first singles qualifier in the Open Era to win a Grand Slam title.

She also holds the record for the least number of majors played in before winning a Grand Slam title.

As if this wasn't enough to astound the majority of us, a recent video posted to Weibo (a Chinese social media platform) shows her addressing her audience in perfect Mandarin.

Raducanu was born in Toronto to a Romanian father and Chinese mother, but moved to England at just two years old.

It is believed she can speak three languages in total, English, Romanian and Chinese, representing all of the cultures she has grown up around.

This isn't the first time fans have seen her speaking Mandarin, however, she also addressed the crowd in Mandarin during her winner's interview at the US Open.

Then, just last week at the Transylvania Open, she wowed the crowd once again by speaking Romanian to them from centre court.

Many tennis fans have also had their say on the up-and-coming superstar and it seems the majority of them are equally impressed.

One fan commented: "She’s a fantastic tennis player with almost global appeal. She’s British, Canadian, Chinese & Romanian. She identifies and relates to all of the above. She’s an incredible role model, fair play to her. She’s fantastic and so very likeable."
