Introduction to Tianshu Lawn: Among the eight lawns in Daming Mountain, Tianshu Lawn is the largest one, with a total area of 180 acres. The most peculiar thing about Tianshu Lawn is that on the rocks covered with moss and miscanthus, there are many uneven lines, which look like words but not words, like pictures but not pictures. They are like miraculous workmanship, hence the name.
