Fallen leaves fly by the lake in autumn: the lake water is rippling with blue waves, and the trees by the lake are already golden, with fallen leaves falling in a flurry. A maple leaf slowly drifted down on the lake, creating ripples in circles. In the distance, a woman dressed in ancient attire is playing the piano by the lake. The sound of the piano is melodious, and together with the fallen leaves and the lake water, she is composing the praises of autumn.
