Tucked away in Tanmen Town, Qionghai, Hainan, there is a unique fishing village: Caotang Village. Here, the locals don't cast nets or bait fishing lines - instead, they dive 20 to 30 meters down, down, down to the seabed, and catch fish there with their bare hands. This centuries-old technique is not only essential for survival, but is also an ancient tradition showcasing the ocean-going wisdom of village ancestors.

In the past, village residents often ventured far into the South China Sea to make a living from their ocean catch. These days, many have bid farewell to the open sea and embarked on a new journey, transforming their fishing boats into sightseeing boats, establishing fishery cooperatives, and changing their professions from fishermen to tour guides, bringing travelers to experience the wonders of the sea.

Meanwhile, on shore, locals are also exploring new ways to coexist with nature. Facing the challenge of barren, coastal, sandy soil, they are making smart use of marine resources, using dried and fermented sargassum seaweed as a fertilizer to grow 'seaweed sweet potatoes'. This organic agricultural product has been named a ‘National Specialty Agricultural Product’ and has also become a popular local specialty attracting many travelers.

With the opening of the new Hainan Coastal Scenic Highway, Caotang Village is welcoming new development opportunities. Visitors can dig up their own sweet potatoes, savor local treats, watch the fishermen dive into the sea, and devour the fresh catch of the day. This coastal village, with a blend of ancient skills and modern vitality, is telling a new story of harmony between humans and the ocean through their unique ways of 'farming the sea'.
