As a teenager he traveled to small villages where the ancient techniques were still being used in an attempt to preserve the age-old art form.
Hung is unique as an artist in that his work was exposed internationally before the formal opening of the Vietnamese economy in the 1990s.
Hung participated in a group exhibition titled Art Spring hosted by Alliance Francis, in Hanoi in 1993.
The following year he established the Avante Guarde group with its first exhibition in Hanoi together with artists Trương Tân, Lê Hồng Thái, and Đỗ Minh Tâm—with support from the German Socialist Cultural Mission.
Since his first solo exhibition in 1995 at Hanoi's Australian Cultural Center, Hung has gone on to represent the spirit of newly emerging Vietnamese artists with innumerable solo exhibitions worldwide, including London, Hong Kong, Miami, Paris, Singapore,[1] and Dubai.
