History & meaning.
The history of Ca Ong worship in Da Nang begins with fishing communities from central Vietnam settling along the coast from the early 19th century. The sea between Son Tra and Thanh Khe was a vital fishing ground but also full of hazard: South China Sea squalls arrive fast and fierce, and the simple wooden boats of the era offered little protection. In this context, reverence for Ca Ong — the largest marine creature fishermen regularly encountered — developed naturally as a psychological mechanism for community protection. Numerous accounts describe whales actually swimming near distressed boats, creating enough current and directional influence for fishermen to find their way to shore. Whether explained biologically or spiritually, those memories embedded themselves deeply in fishing village culture and have not faded across generations.
The three ritual phases of Le Te Ca Ong reflect three layers of fishing village spiritual life. The Ca Ong procession takes place at pre-dawn — the most sacred moment, when the boundary between the human world and the sea deity's domain is considered thinnest. The procession wears ceremonial dress, carries the five-element flags, and leads drums and gongs toward the water. The sea deity ceremony follows in the afternoon, with ancient invocations in Nom script read aloud by village elders — today many participants no longer understand each word but maintain the original text exactly, believing Ca Ong understands regardless. The final phase — honouring the fishing village ancestors — is the most emotionally charged: names of fishermen lost at sea are read aloud in absolute silence. In Man Thai village, this list dates to the French colonial period, recording those who never returned.
Da Nang's whale funeral custom is something no other place in Vietnam practises in precisely the same way. When a whale washes ashore dead, the person who first discovers it — whether a fisherman or an ordinary resident — immediately becomes Ca Ong's 'eldest son.' This title is not merely symbolic: that person must genuinely go into mourning, wearing white clothing and a white mourning headband, and presiding over the entire burial ceremony. The whale's remains are interred at the beach or in the grounds of the village shrine. After three years, the bones are exhumed, placed in a carved wooden reliquary, and permanently enshrined in the lăng Ông. The communal halls of Tho Quang and Man Thai today preserve whale skeletons from the 19th century — genuine 'ancestors of the sea' worshipped by humans with the same devotion given to family members.
Attending Le Te Ca Ong is a multi-sensory experience completely unlike any other festival in Da Nang. Sandalwood incense blended with sea salt fills the communal hall in the pre-dawn darkness. Drums and gongs leading the procession resonate through the dim early-morning air, mixing with the sound of distant waves. The white of ceremonial robes and mourning headbands contrasts with the red of ceremonial flags and lanterns. The faces of village elders — many in their seventies and eighties — carry a solemnity that cannot be performed. And in the midst of it all, during the reading of names of those lost at sea, there are silences so dense that even an outside observer can feel the weight of collective memory present in the space.
Ca Ong demands nothing from the sea — He gives everything.

Highlights not to miss.
Throughout the more than 200-year history of Le Te Ca Ong in Da Nang, seafood has never once been presented as an offering — remarkable for a community that survives by fishing. The fishermen's explanation is both simple and profound: Ca Ong is the lord of the sea; the ocean and everything within it belongs to Him. To offer fish to Ca Ong is an unacceptable paradox. This rule is the key to understanding the deeper spiritual philosophy beneath the visible ritual forms.
When a whale washes ashore dead, the first person to find it becomes 'eldest son' and enters genuine mourning — wearing white mourning dress, presiding over burial, and returning three years later for the bone reinterment ceremony. The whale's bones are then enshrined in the lăng Ông — actual brick-built mausoleums constructed specifically for whales. Man Thai and Tho Quang villages still preserve 19th-century skeletons. This is the only custom in Vietnam that treats a wild animal with the same reverence accorded to human ancestors.
The Cau Ngu ceremony at Da Nang's fishing villages was inscribed as a National Intangible Cultural Heritage by the Ministry of Culture, Sports and Tourism in 2016. This places it alongside Hue royal court music and Phu Tho xoan singing — heritages prioritised for preservation and scholarly study. The inscription has encouraged multiple fishing villages to fully restore ritual phases that had been abbreviated during the 1980s–90s, and has motivated younger generations to assume roles in the ceremony.
The Ca Ong mausoleum at Man Thai village (Ngo Thi Si Street, Son Tra district) is open year-round and houses whale skeletons from the 19th century. Visiting the mausoleum before the festival date will give you a much deeper understanding of the entire belief system before witnessing the actual ceremony — and there is usually a caretaker willing to share stories if you approach with genuine curiosity and respect.
How to attend & get there.
How to Approach and Attend
Le Te Ca Ong is held at Man Thai communal hall (Son Tra district) and Tho Quang — the two venues with the largest scale and the most complete three-phase ritual. The pre-dawn period (4:00–6:00 AM) is the most atmospherically beautiful but requires rising before daylight and travelling in darkness. The afternoon from 2:00–5:00 PM hosts the main formal sea deity ceremony and is more accessible.
Respectful Conduct
Wear long-sleeved shirts and long trousers in neutral colours — absolutely avoid red (reserved for ceremonial ritual dress). Do not cross in front of those performing the ceremony. Ask permission before photographing — many families do not wish their children or elders to be photographed during sacred moments. Disable flash entirely inside the communal hall. If possible, arrive with a local guide who has community connections.
