The Main of Life is a catalogue of extraordinary printmaking techniques. It first creates the lines of the Chinese character "囍" (lit. wedding) using Relief-printing techniques, then prints the image of the grass and the large red cross with silk-screening techniques, before finishing it off with the image of the wild goose using techniques of metal Intaglio and Relief printing. Such combinations of artistic components and printmaking techniques enhance the diversity in visual effects. In particular, the symmetric composition signifies great respect for the symbolic meanings of "the main of life", which involves basic human needs such as eating and sexual desire.
