Within the cultural complex of Hue, if the system of palaces and royal tombs defines the face of an Imperial capital, the villages along the lagoon and coastline preserve the depth of community life. There, heritage does not lie dormant in the past but lives on in every festival season, every daily custom, and every belief tied to the natural environment. The Cau Ngu Festival of Thai Duong village, held once every three years in January at the Thuan An seaport, is precisely such a heritage - a vibrant cultural practice where community memory, maritime knowledge, and the will to survive have woven together into an enduring whole across hundreds of years.

On the morning of February 28 (the 12th day of the first lunar month in the Year of the Horse), at the Thai Duong Cultural Village Communal House in Thuan An Ward, the 2026 traditional Fish Worshipping (Cau Ngu) Festival officially opened in a solemn and vibrant atmosphere, attracting a large number of People, fishermen, and visitors.

That is the vast green casuarina forest that the people of Thai Duong Thuong village (formerly Hai Duong Commune, now part of Thuan An Ward, Hue City) planted decades ago to shield them from the winds, stop the sand, and protect the village. Amidst the vast sky and land, the casuarina trees grow lush and strong, becoming a sturdy shield, guarding the village from waves and winds, and the harshness of the sea.
