HÀ NỘI — Vietnamese acrobatic artists Giang Quốc Cơ and Giang Quốc Nghiệp, internationally known as the "Giang brothers", have set a world record in their last international performance in a Guinness World Record show in Milan, Italy. "It is a world record because it will be the first time this act is performed to the world public," Cơ told Việt Nam News prior to their trip to Milan. Winning the world record brings a difficult-to-describe feeling to us. There will be no more Quốc Cơ - Quốc Nghiệp internationally, but I feel so grateful to everyone," he said. Previously, Cơ and Nghiệp set two Guinness World Records.
