In the middle of the photo,a small brook meanders along the valley. The brook is about one-meter wide. The water is quite clean, which can clearly reflect the sky as well as the trees around it. At both sides stand many trees, some are standing still while others are falling down. There is one large tree lying above the brook, placing its two heads on the high ground. Besides, some small branches also lying across the brook. In a word, you can see many branches across the brook, some are above it and some are half-in it. It is autumn at that time. Hundreds of red leaves are lying on the ground, with some green moss mixed up. There is one large stone in the left side of the brook, with green moss covering the surface of the stone.
