Introduction to the cloud shadow in the center of the lake: The cloud shadow in the center of the lake is one of the eight scenic spots in Xianghu Lake. On a sunny day, we climbed to Yahu Mountain in the center of Xianghu Lake. But I saw that the surface of the lake was like a mirror, with the blue sky and white clouds reflected in the lake, and aquatic plants and fish swimming through the clouds. The cloud shadows are different in the morning and dusk, and in the four seasons. The scene is poetic and picturesque, endlessly changing.
