Yandunjiao Swan Lake is a Yellow Sea bay between the ancient Yandun site Lushan Island and the first strange stone in the Chinese sea, less than one square kilometer. Every time the cold wind and snow, the large swans in groups come here, in the blue waves of the bay, or wander freely, or chase the water, or lead the song, or fly in the sky, or dance, people like a fairyland, like a dream.
