Off the coast of Zhuanghe lies a clam-shaped islet. Old fishermen say it was once a fairy in the form of a giant clam: during a terrible autumn storm, a shallow bank surfaced, densely packed with silver-glimting clams, holding back the waves and saving the fishing boats. After the storm it grew into an island — a shelter ever since. Around it the water is clear and the flats gentle; at low tide clams and cockles lie thick. Listed as a fishing ground since the Ming-Qing transition, the islet is nicknamed ‘Little Guilin on the Sea,’ and its tale is still told with the tide.
