The President of the Shiy De-jinn Foundation, Dang-ho Liu, wrote: "Mr. Shiy De-jinn was born in Szechwan, and educated there and Hangchow in Mainland China. Then, he moved to Taiwan. At the beginning he lived in Chia-Yi and later in Taipei. Shiy had visited the United States and lived in France for three years. In August 1981, he died in Taipei. Shiy De-jinn's painting style went through several stages. While Shiy was studying at the Hangchow Academy of Arts, his style was influenced by Lin Fengmian. His paintings of that time showed a sensation of elegancy and softness. He brings out rhythm and movement from the tranquility, with slightly curved lines.

For a period of time, Shiy's style changed and became cold and hard, Works of that period are similar to the works of Buffet. They are characterized by dark straight lines; they might look like rough drafts, composed of experimental sketches. However, each subject he depicts is complete. After several changes of style, Shiy's works evoked the motive and inner spirit of Chinese ink colors. His paintings of that time are characterized by softness and denseness. This change made his works very similar to the abstract paintings of Zao Wu-ki in the way that they both create from the spirit of Chinese ink paintings, this period is known as Shiy's abstract period.

Shiy's works derived from a mixed style of world masters. For example one can detect the elegancy of Botticelli, Courbet, Rembrandt and El Greco in his works. Shiy also absorbed the use of primitive color, simplicity and boldness of the Fauvists. He also learned to use Picasso's use of primitive color and shapes. From Klee's works, he added to his own works a sense of tranquility. From Hard-Edge works, he transplanted the flat colors and defined forms."
