Shiy studied in the United States for a year and in France for three years. Returning, he found renewed inspiration in the scenes of Taiwan. Although he is perhaps best known as a painter of landscapes, he is also among the very best portrait painters of modern China. He has enjoyed painting young boys, leaving a touch of melancholy in their expressions. Shiy's watercolors are replete with luminous color. His flowers lose the stiffness to be found in much Chinese representation. A critic has written that "Each blossom, each leaf, even the stems which pattern much of the surface, have an explosive intensity that immediately competes for the viewer's attention." His other subjects include houses and usual objects of Chinese life. Landscapes are never dull. They have an inner glow that gives mountains and mists a merging wholeness rare in Chinese painting today. His trees reflect centuries of Chinese tradition and his buildings are clearly of Chinese style architecture.
In the view of Shiy De-jinn, "The natural landscape in Taiwan surpasses that of southern mainland China in variety and at least equals it in beauty. This is the most precious place in south western China." The painter has found early morning and dusk to be his favorite times of the day. He leaves city and studio for the mountains that he loves so well and paints so majestically. His art arises from the land and people in the same manner as a long line of Chinese painters stretching back through hundreds of years of history. He will be sorely missed in China, not only for his work but also for an inspiring career of teaching.
