It can be said that Tran Luu Hau is one of the prominent artists of Vietnamese who is infatuated with Expressionism and also the pioneer generation in inspiring young Vietnamese artists. If Impressionist artists admire the beauty and harmony of natural colors, artists follow Expressionism like Tran Luu Hau would choose a very different direction. They choose to go deep within themselves, experience and then bring their inner voice to the world through art.

"Simple Beauty" is a "symphony" in colors, harmony with powerful and impressive brushstrokes. Art critic Nguyen Quan once said: "The life, the grandiose art career, the dedication is the quality that made Tran Luu Hau become a master in art".
