Among the 8 pieces of lawns in the mesa in the Daming Mountain, the Lawn of God's Book, with its total area up to 180 mu, is the largest one. It is full of wonder that many concave and protruding lines are distributed in this lawn. They seem to be characters but actually not, seem to be pictures but virtually not; they seem to be carved by manpower, still they seem to be the work of the god. "God's Book" is thus named. It is said in fables that the Daming Mountain is the place where gods get together, they talk over classics, discuss on truth, recite poems, and play chess here on the bright night or foggy seasons. And these lines are believed to be the "God's Book" left by them unconsciously.
