What Are Whale Worship and the Cau Ngu Festival?
Whale worship (also called the Nam Hai deity) is the practice of coastal residents honoring whales as guardian deities, building tombs, communal houses, and shrines for worship and offerings. The Cau Ngu festival is a collective ritual held after Lunar New Year each year, as the new sea season begins, to thank the Nam Hai deity, remember ancestors, and pray for a favorable fishing season. The two are closely linked: the Cau Ngu festival originates from whale worship and takes the offering ritual at the whale shrine as its most important part.
Origin and Formation
Whale worship in the South Central Coast has no precisely identified starting point. According to elderly coastal residents, the custom dates back to ancient times and has become a folk cultural belief. Researchers note that Nam Hai deity worship among the coastal people of Khanh Hoa dates back very far, based on the presence of horizontal plaques, large characters, parallel sentences, orations, and especially royal edicts at many relics.
The earliest royal edicts for the Nam Hai deity in Khanh Hoa were found dated to the 3rd year of Minh Menh (1822) at relics such as Binh Tan communal house, Xuong Huan communal house (Nha Trang), and Lang Truong Tay communal house (Ninh Hoa). The latest edicts date to the 9th year of Khai Dinh (1924). These are villages and communes with early formation histories in the province's geographical records.
Archaeologically, the Bich Dam site on Hon Tre island (Vinh Nguyen ward, Nha Trang City) was excavated and identified as belonging to the Xom Con - Nha Trang culture, dating back over 4,000 years. This is a typical maritime culture in Khanh Hoa, considered a bridge connecting contemporary cultures in the Dong Nai River basin with the central region and Central Highlands. Xom Con culture is a sea-oriented culture, one of the origins of Sa Huynh culture, showing that maritime thinking has been deeply imprinted in the cultural marks of people on this land for thousands of years.
Formation Mechanism and Characteristics of South Central Coast Maritime Culture
The culture of coastal localities in the South Central Coast formed from the exchange and acculturation of economy, culture, and the spiritual life of sea-oriented residents. These values have been preserved through generations and are clearly shown in traditional fishing, festivals, and community folk beliefs.
The maritime cultural elements of the Vietnamese are the result of agricultural residents' adaptation as they moved from river mouths out to sea. This process created a distinctive character with a deep, reserved, intense inner nature and a gentle, flexible, kind outer nature. In many coastal villages of the South Central Coast, maritime cultural values and spiritual life are always tightly linked and become an anchor for fishermen's own soul.
The characteristic of maritime culture is spiritual culture. Whenever they go to sea, fishermen always believe there is a mother protecting them from storms. Mother Goddess worship is a root of the Vietnamese people, but upon arriving in this land it blended with Cham culture, so South Central Coast fishermen formed a new culture with a feminine character. These same fishermen created many forms of literary and artistic expression such as ho ba trao, bai choi, hat boi, and the art of hat chau van, hau dong, mua bong, and the cau ngu festival to serve their spiritual and cultural life.
How Is the Cau Ngu Festival Held?
The Cau Ngu festival is held by coastal fishermen around the time after Lunar New Year each year, as the new sea season begins. The purpose is to thank the Nam Hai deity for supporting fishermen on their voyages, to remember ancestors, and to pray for national peace and a good catch in the new sea season.
The most important part of the festival is the offering ritual at the Nam Hai deity shrine. The ritual is presided over by four men: chief celebrant, assistant celebrant, left rank, and right rank, along with four student celebrants offering wine and lamps. The festival opens with a procession bringing the Nam Hai deity to the shrine and ends with the Tong Na offering, meaning sending the deity off.
The Cau Ngu festival preserves many traditional customs such as the edict procession, the welcoming of the Whale, ho ba trao, the tinh sanh ritual, and the main offering. It is a synthesis of traditional cultural activities, including the Whale welcoming at sea, the offering ritual at the shrine, the royal edict procession, ho ba trao, and hat tuong. The festival also brings together traditional performing arts and folk performances such as hat boi, ho ba trao, mua sieu, and folk games, creating a vivid picture of a fishing village festival.
System of Nam Hai Deity Relics: Scale and Distribution
According to a survey by the Khanh Hoa Provincial Center for Relic Conservation, at the time of publication, Khanh Hoa province had 52 facilities, relics, and worship sites for the Nam Hai deity. Among them, 13 relics have royal edicts with a total of 62 edict entries for the Nam Hai deity.
The Nam Hai deity in Khanh Hoa and other coastal provinces of the central region is worshipped in very diverse types of relics such as tombs, communal houses, shrines, and temples. The deity may be worshipped independently or jointly with other deities in the same relic. Accurately identifying the name of the Nam Hai deity and the worship facility is important for determining the subject worshipped at the relic and the people's belief practice, especially whenever a festival takes place.
Currently, Nam Hai deity worship mainly relies on legends and stories associated with figures such as Guanyin, Quan Cong, and the Cham sea wave deity Po Riyak. This diversity reflects the long process of cultural exchange among coastal communities.
Specific Example: Nam O Fishing Village and Cham - Viet Traces
Nam O fishing village (Lien Chieu district, Da Nang City) is a typical case of transition between two cultures, Cham and Viet. Many traces of multiple cultural layers remain here, preserved by villagers such as the Cham water well, Am Linh shrine, the temple of Princess Huyen Tran, and Lang Ong Nam O.
According to residents who have studied this land, it is unclear when Nam O village was founded, but it can be affirmed that the ancient owners of the village were Cham people who lived by fishing. From this cultural acculturation, the fishing tradition and whale worship custom have been preserved by villagers. Also from maritime beliefs, villagers have buried and worshipped many whales.
The Da Nang Museum has dedicated a space to recreate and display the people, culture, and maritime cultural festivals. Images such as the ghe bau, characteristic of Quang region people in particular and South Central Coast maritime residents in general, along with the cau ngu festival, are introduced as the most typical beauty in the spiritual life and cultural activities of South Central Coast fishermen.
Comparison Between Localities in the Region
South Central Coast localities share the same foundation of whale worship and the Cau Ngu festival, but are not completely uniform in scale, ritual, and degree of blending with indigenous cultural elements. The table below summarizes some differences noted in reference sources:
| Locality | Noted Characteristics |
|---|---|
| Khanh Hoa | 52 Nam Hai deity worship facilities; 13 relics with royal edicts totaling 62 edicts; earliest edict dated 3rd year of Minh Menh (1822), latest 9th year of Khai Dinh (1924); Cau Ngu festival recognized as National Intangible Cultural Heritage in 2014; Mother Goddess worship holds an important position; Thap Ba festival recognized as a national-level cultural heritage |
| Da Nang (Nam O) | Traces of Cham - Viet cultural transition; Cham water well, Am Linh shrine, temple of Princess Huyen Tran, Lang Ong Nam O; Da Nang Museum displays maritime cultural space; ghe bau is a characteristic image |
| Quang Ngai (Ly Son) | Fishermen's boats tied to island life; part of the South Central Coast maritime cultural region |
Reference sources do not provide a common standard for the Cau Ngu festival ritual in all localities. Differences in festival scale, number of relics, and degree of joint worship reflect each place's own historical, demographic, and cultural exchange conditions, not superiority or inferiority.
Cultural Value and Contemporary Life
The Cau Ngu festival and Nam Hai deity worship express the beauty of folk culture of coastal residents. The festival is a cradle and source of nourishment for the folk and traditional culture of the South Central Coast, contributing to the foundation for building the cultural identity of this land.
Preserving and promoting the value of the Cau Ngu festival contributes to safeguarding traditional culture, educating love for homeland and country, and proving the process of conquering and mastering the sea and islands by Khanh Hoa fishermen in particular and Vietnam in general. The maritime cultural space displayed at museums is also a community cultural activity, an authentic archive of evidence related to sovereignty and fishermen's experience in dealing with the sea over generations.
In terms of daily life, the Cau Ngu festival is also an occasion for fishermen to meet and wish each other full holds of shrimp and fish on their voyages. The sea brings abundant resources but the working environment contains many risks and uncertainties, especially during the rainy and stormy season. Therefore, in traditional fishing activities, fishermen have their own forms of worship to pray for favorable weather and protection by deities on their sea voyages.
Points to Note When Researching
First, whale worship and the Cau Ngu festival are folk belief cultural practices, not a tightly organized religious doctrine system. Reference sources describe this as a folk cultural belief, based on legends and stories.
Second, the timeline of the belief's formation is not precisely determined in the sources. The earliest royal edicts found date to 1822, but that does not mean the belief only began then; it only reflects the earliest documented milestone still preserved.
Third, the diversity in worship and ritual between localities is a natural characteristic of a large cultural region, and one locality should not be taken as the standard to evaluate others.
