Mr. Feng started creating framed cartoons in September 1935 and published them in the magazine "Universal Wind". The subjects of his creations include all aspects of life: babies, students, poets, coolies, tourists, illiterates, and almost all social strata. By the end of the 1940s, the theme of Mr. Feng's four-title paintings had returned to innocence from all aspects of society. These four-topic paintings reflecting children's themes were published one after another, mostly in Hong Kong. In October 1979, they were collected and published under the name "Feng Zikai Comics". This book collects four-frame comics created by Mr. Feng in various periods, and selects 80 groups of comic strips. From the background of these paintings, it seems that his era has passed. In fact, the paintings also contain the eternity of history and human nature.
