In August 1953 , Wu competed at the 4th World Festival of Youth and Students in Bucharest , Romania . He won the 100 metre backstroke with a time of 1:06.4 . His victory was so unexpected that the swimming organizers did not have a recording of the Chinese national anthem and had to borrow one from the athletics organizers . This medal ceremony was the first time that the flag of the People 's Republic of China was raised at an international sporting event
