When the first rays of morning light pierce through the sea fog, the tidal flats of Beijingzi Town, Dandong City, Liaoning Province, reveal a captivating scene. In sunlight, tiny shells sparkle like stars. Parents hold their children’s hands and stroll along the beach, leaving a trail of footprints in the shallow waters. Tourists, equipped with small buckets, shovels, and other tools, search for seafood, such as clams and mussels, hidden in the sand and mud.
