Moving to Paris could be the most important event in the long span of Chu's art career, there were many schools of western abstract paintings since the late '50s, and many of art were influenced by eastern philosophies. Chu went to Paris with his profound oriental thinking, and absorbed the postwar western cultures. Maybe it's due to his modest characteristics, add his later established abstract painting style some western particularities, and this unique style is not the result of using only what he's good at.

Unlike other artists, when Chu commences to paint, he doesn't set a theme or create a scratchy form beforehand, but absolutely free and unrestrained isn't the attitude for such an artist who placed paintings as the most important thing in his life as well, the source of his paintings came from his understandings of nature, he discovered his love for nature, and this stimulates him to paint. When standing in front of the canvas, the artist can no longer hide his feelings, from a viewer's point, their private feelings could be encouraged, although there are titled for each of Chu's paintings, however the viewers can still keep their own way of sensing, to dig, to run in, or even to study it, and what Chu created is an organic environment on the canvas, all the characteristics or ways of thinking could find their place to be released.
