Le Sang was born to Le Van Hien (also known as Duc Quang) (1887–1959) and Nguyen Thi Mui (1887–1993).
He was ill as a child, which made it difficult for him to walk, and his mother advised him to study a martial art in order to strengthen his legs. In Hanoi he learned Vovinam at Nguyễn Lộc"s Vovinam school. In 1954 Le Sang accompanied Nguyễn Lộc to Saigon to open a Vovinam class.
He continued to open additional Vovinam schools and, as of 2007, was still teaching the higher-ranked students.
In 1960, Nguyễn Lộc passed the leadership of Vovinam to Le Sang. After the fall of Saigon he spent several periods in prison.
Leadership passed to Trần Huy Phong (1938-1997). He was born in Hanoi, Vietnam and died in Ho Chi Minh City.
