From the age of wooden sailboats to the thunder of modern engines, and now to satellite navigation in the digital era, the sails of Tanmen's fishermen have never left the South China Sea. Each year, during the fishing season, they continue to follow the routes charted in Geng Lu Bu, keeping alive their bond with the sea. These faces carved by ocean winds and stories soaked in saltwater form a vivid chronicle of the Chinese people's enduring tradition of seafaring and fishing in the South China Sea.
