Blazing red seepweeds, vast reed marshes, dancing black-billed gulls, giant rice paddy painting... In Panjin City, the capital of wetland, a large number of tourists from all over the country come to Red Beach National Scenic Corridor to appreciate the scenery and take photos. Flocks of gulls and herons are spreading their wings and soaring in the sky. They sing, dance and play, like leaping notes to perform a summer song.
