The impressive performance from Giang Quoc Co and Giang Quoc Nghiep on June 3 made viewers breathless and then put them on their feet applauding.
All four members of the jury showed their admiration for the performers.
Although not winning the show, the performance was a hit for British audiences watching on ITV.
Last month, the duo stunned the audience of Britain’s Got Talent with a mind blowing balancing act in front of a live studio audience and millions of people watching at home.
Britain's Got Talent is a UK talent show. The programme was created by British reality TV star Simon Cowell, which began in 2007.
The winner of Britain's Got Talent 2018 was Lee Ridley - a disabled person who cannot speak. His performance featured "chatting" with the audience through a tablet, with his subtle humour causing laughs aplenty.
The prize for the winner is £250,000 (US$334,281) in cash. The winner will perform in front of the Queen and Royal Family members at the Royal Variety Performance.
