Zhu Derun's painter inherited the painting schools of Li Cheng and Guo Xi of the Northern Song Dynasty, and at the same time paid attention to observing nature and teaching the creation of the law as the material for his own creation. He said that "when the wind and the sun are beautiful, and the flowers are with the willows, looking at the mountains and rivers and forests far and near, feeling the changes in the grass and trees in spring and summer, the morning and evening, far and faint and near, with the high view, it is enough to be happy and innocent and suitable for the prosperity" ("The Collected Works of Cunfu Zhai"). Try to see from the "Forest Under the Sounding Qin Diagram", painting mountain wrinkles like cirrus clouds, writing tree bald branches like crab claws, light smelting and clear, light smoke dream fog, these are Li Guo's legacy; The center stroke of the calligraphy seal is combined with the realistic performance, and it does not make a slender depiction and exquisite rendering, which is different from Li Guo.
