Starting the artistic process with Painting, Kim Duy questioned the hidden layers of color and form, the contents of art contained in words. His creations with ballpoint pens inscribed on canvas began in his early years at an art academy in Germany, and since then Duy has continued to pursue visual arts with a focus on content and ideas, using words and phrases. language as a creative material for the visual arts. Duy's compositions dissect the concept of complete words, disassemble the word structure back to the state of arrangement, and transform them from being read to being seen. 

Duy's artistic practice experimented with a variety of objects and materials such as printers, paper cutters, napkins, ballpoint pens, markers, etc. to more traditional materials such as pencils and paper. His works have been featured in group exhibitions, open studios of Nha San Collective, MoT+++, Heritage Space, etc..
