I have always thought that Gansu is a land of desolate and ridiculous, so that the mountains and rivers and trees are in harmony with each other, and it is also so gentle and tender.

Li Ke-dy's "Western Narrow" is one of the three best-selling Chinese calligraphy, and is the best preserved treasure in the ancient cliff stone carvings. .
