This series of works can be divided into three types of themes. They are the “Ink and Wash Series on Paper” with the most style of Chen San, adding directional elements to the ink and wash images that Chen San is good at, such as yellow light, orange circles, The landscape lines of the quick brushes, leave our imagination to flow and extend. The chaotic “War Series”, which combines Chen San’s bold color habit and novel composition method in the past, shows the artist’s understanding of disputes in the stream of consciousness The figurative and abstraction; the “color block series”, which is mainly based on clear color blocks, uses a large number of uniform and flat paint to express the warmth of the world and convey the soft power in the face of disasters.
