Cheng was born in Shanghai. He enrolled at the Shanghai Academy of Fine Art (上海美术专科学校) in 1938, where he was mentored by several teachers, Wang Gefang (王个簃), Li Zhongqian (李仲乾) and Wang Shengyuan (汪声远). Li Zhongqian gave the name “Shifa” to Cheng, who continued to use this moniker throughout his artistic career. Cheng graduated from the academy in 1941. Shortly after the liberation of Shanghai in 1949, he joined the Shanghai Peoples’ Fine Arts Publishing House (上海人民美术出版社) as a professional artist and the Shanghai Chinese Painting Academy (上海中国画) as a teacher in 1956. He became its President in 1984 and remained their honorary President in his twilight years.
While still life is an art genre typically associated with oil paint and realism, Cheng attempted to break away from these norms by rendering a flower arrangement in Chinese ink in the calligraphic style. Varying hues of greys and pinks spread to create an amorphous image of blossomed flowers with leaves. By contrast, Cheng delineated the vase’s contour and details its ornamental patterns in dark calligraphic strokes.
