The sky, the mountains and the lake are divided into three equal parts, extending the view of the mountains and the open lake in front and behind. The dense color and contrasting cold warm colors complement each other, forming a bright and harmonious atmosphere. The latitude and longitude dimensions and the size of the space are repeatedly reinforced by the direction of the moving clouds and water, the trajectory of the white sails and passenger boats, and the extension of the mountains and the lake.

Comparing with the watercolor sketches of the previous three years, or the three works painted around the same time, we can see the artist's principle and expression of using points, lines and surfaces to form space, with a flexible and unique approach. Another element is the effect of the light source in front of the viewpoint, i.e., backlighting. The quality of light changes according to its own time, and radiation or illumination is different in its own way, but the childhood humor is also hidden in it.
