The painter Tran Hong Duc has created an emotional structure in his painting “City on the sea” which is the depth of space, the movement of surface, the opening of a full and bright life in a space where fresh blue is the dominant background. With strong brush strokes and emotions, they created a strange charm for the painting. His artistic career that Tran Hong Duc has pursuited for many years is enough for us to see his passion for the abstract style.
