As the temperature drops, tens of thousands of whooper swans fly from Siberia, Mongolia and other places to Shandong Rongcheng for wintering. At present, the number of whooper swans relocating for winter has reached more than 200, bringing new life to the coastal city. (Yang Zhili/Guangming Picture)
