He was adopted as an adopted son by the court painter Li Congxun, taught painting skills, and eventually became a generation of famous artists. The painting academy of the Three Dynasties (1190-1264) of Song Guangzong, Song Ningzong and Song Lizong was to be edicted, and he was respected as the "Old Painter of the Three Dynasties". Gonghua characters are explained, and they have to be trained from the will, especially in boundary painting. The figure paintings are meticulous and energetic; the paintings of flowers and birds are exquisite and rigorous, and they do not feel cumbersome and sluggish; landscape paintings are operated by craftsmen, leaving the image outside, fascinating; boundary paintings do not use boundary rulers, and the rules of the palaces and pavilions are prepared with rope and ink, which is extraordinary. The subject matter of painting is rich and colorful, from the court to the folk, from the city to the countryside, from production to life, from eating and drinking to entertainment, from the Xianshan to the Dragon Palace, from history to reality, which are reflected in the paintings, to reflect the rural terroir and peasant life. For example, Ming Emperor Fighting Diagram and Flower Basket Diagram; there are custom paintings with white depictions and pale colors, such as Cargo Lang Diagram; there are also landscape paintings rendered with ink, such as West Lake Diagram and so on.

The "West Lake Picture Scroll" is a Chinese painting work by the Chinese Song Dynasty painter Li Song, this West Lake picture is not necessarily the most exquisite picture scroll depicting the West Lake since ancient times, but it is the work that best illustrates the whole picture of the ancient West Lake.

According to The Fifth Volume of Li Yan's "Southern Song Dynasty Painting Catalogue", Zhu Yuanzhang once wrote an inscription on this "West Lake Map" and praised it, as a Taizu Emperor who had not received compulsory education and relied on self-study to get rid of blindness, he was usually very interesting, and rarely engaged in literature and art in takeaway, and this seemed to be the only direct comment on painting works that people knew Zhu Yuanzhang.
