-lofty, far-reaching, far-reaching.

Guo, a famous painter in the Song Dynasty, defined the method of "three distances" in Lin Zhi: "A mountain has three distances: from the foot of the mountain to the top, it is high; Looking at the mountain from the front is far-reaching; Looking at the distant mountain from the near mountain is called the plain. " Three-distance method is a kind of time-space view, which depicts the scenery in the painting from different viewpoints such as looking up, looking down and looking up, breaking the limitation of observing the scenery from one viewpoint, that is, focus perspective. The theory of "three distances" not only summarizes China's perspective of landscape painting, but also embodies the unique spatial aesthetic consciousness of China painters.
