The Four Gentlemen have been used in Chinese painting since the time of the Chinese Song dynasty (960–1279) because of their refined beauty, and were later adopted elsewhere in East Asia by artists in Korea, Japan, and Vietnam. As they represent the four different seasons (the plum blossom for winter, the orchid for spring, the bamboo for summer, and the chrysanthemum for autumn), the four are used to depict the unfolding of the seasons through the year.
