Guo Xi (about 1- 19) was an outstanding painter and painting theorist in the Northern Song Dynasty. Chunfu was born in wen county, Heyang (now Mengxian East, Henan). He was born a commoner, believed in Taoism in his early years, traveled abroad and was famous for his paintings. In the first year of Xining, he was called into the Painting Academy, and later served as Hanlin. The landscape teacher, Fa Licheng, created a brush with the shape of a cirrus cloud, which was later called "cirrus cloud". His paintings of mountains and rivers pay attention to in-depth observation of life, which can truly, meticulously and subtly show the characteristics of different regions, seasons and climates, and he has created an extremely rich, beautiful and moving artistic conception. In addition, he is good at shadow sculpture, and he uses mud to pile up embossed mountains and rivers on the walls, which is unique.

Guo Xi has been handed down from generation to generation such as Early Spring Map, Chun Xue Map of Guanshan Mountain, Pingyuan Map of Nested Stone, Valley Map, and Remote Mountain Map of Ancient Wood. Among them, "Early Spring Map" successfully shows the detailed seasonal changes of winter leaving and spring coming, the earth reviving and everything waking up. Guo Xi has also made great achievements in painting theory, and his theory is reflected in his book Lin Quan Gao Zhi.
