In the late 1980s and the early 1990s, in the series "the aesthetics of flora" which Yang Chi-Hung himself called, he returned to the harmony of the universe to express a kind of romantic ambience which is rationality having been internalized through poetic iconography. During this period, the things and their images in Yang's paintings is more than things and their images. They are rather the element of poet which had been filtered from external affairs through time. What we can see was the changes of nature and plants over time, and they were also vividly demonstrated with the directions of Yang's strokes.

"Breaking the Waves" was made in 2007. Back than Yang Chi-Hung's aesthetics of flora had experienced more than a decade and had become more sophisticated. The appearance and color in this painting still inherit his old style using main color of the earth and wave. But the abstract approach to the morphology of the waves and the natural environment has changed. The artist intentionally blurred the concrete images, successfully making the intensity when sky, earth, and sea come to an encounter. Both big unrestrained strokes and minute spots on the canvas bring the painting greatness and delicateness.
