Nature is a great artist, painting the surroundings red and yellow whenever the right time comes. This is an autumn avenue paved with a layer of brittle leaves and tender grasses with gleaming dew hanging at their edges. For students, nothing will be more pleasant than trampling on the golden rug and taking a breath of fresh air. They are amazed by the scenery and feel speechless, as if languages are flattened onto the ground together with the leaves and grasses to add extra colours to the sidewalk.
