This work is dominated by mountains, with towering peaks and rugged peaks. There are countless pines and cypresses standing in the mountains, with luxuriant branches and leaves. There are several dwellings built among the forests, scattered at the foot of the mountain and the mountainside. A figure stood in the open, looking up into the distance. The peaks are alternated with reality, and the white space gives people a sense of immortality. The paintings are quiet and far-reaching, and the painting style is fresh and refined.
