Shiy De-jinn believed that the ever changing landscape always rendered him a powerful strength. His close friends often went along with him. With a pair of sharp eyes that were good at capturing beauty, he always situated himself at the most beautiful area and waited for the perfect amount of fog to appear in order to capture the wonderful color and atmosphere of the scenery. Many art critics believe one of his artistic achievements lies in expressing mountain scenery in Taiwan with modern Chinese painting style.

Fascinated by Taiwan's natural landscape, Shiy once said proudly that "The mountains here are Taiwan's mountains as well as Shiy Dejinn's. The strokes and ink here are calligraphy developed in Chin and Han, but it has an artistic concept of modern China. Since I have a good accompaniment in painting, I can grasp precise shapes. Because I am versatile, my watercolor combines the richness of oil painting and the spirit of ink wash. Other watercolorists cannot produce such a painting, and Western painters cannot create the ridgeline of my mountains and rivers, either. They are the fruit of my diligent practice in calligraphy. Each turn has its own significance. Each pause possesses its own spirit. This is modern Chinese painting, a typical creation of Shiy De-jinn."
