The Yuan Dynasty was established, the country was unified, and the nationalities were integrated. However, due to the late rulers' ethnic discrimination policies and political corruption, many literati are in a frustrated situation and can only pin their feelings on painting and calligraphy. In painting, they pay attention to the expression of subjective interest and pen and ink style, and poetry, calligraphy and painting are further infiltrated and combined, which has pushed the literati painting since the Song and Jin Dynasties to a climax. This is written by Zhao Mengfu, Qian Xuan, Yuan Sijia and Erwang. In addition, due to the rulers' use and protection of religion, the scale of temples has been expanding, so murals have also shown a considerable scale of development. During the Ming and Qing Dynasties, landscapes, flowers and birds, and freehand brushwork figures further developed. At this time, some western painting methods were incorporated into the figure painting, and the level was greatly improved. Folk printmaking and New Year pictures are unprecedentedly prosperous.
