On March 31, Long Hai Commune People's Committee (HCMC) said that taking place in 4 days from March 27 to the end of March 30, the Dinh Co Festival 2026 held in the area attracted more than 230,000 people and tourists to offer incense and worship, experiencing exciting and attractive activities.
In which, on the morning of the main day of March 30th (the 12th day of the 2nd lunar month), thousands of people gathered from early morning to witness firsthand the Nghinh Co ritual, carrying the long position and throne from the sea to Dinh Co. This is also the main ritual of the Dinh Co Festival in Long Hai. After the ritual took place, more than 40,000 people and tourists came to the Dinh Co cultural and historical relic site to offer incense and pray for good luck and peace for their families.
The festival originated from the late 18th century, associated with the process of reclaiming and establishing coastal villages. Over time, Dinh Co Festival in Long Hai has become a spiritual support, a place to send the trust of fishermen, and has been recognized as a National Intangible Cultural Heritage since 2023.
According to legend, from ancient times, a young girl named Le Thi Hong encountered an accident at sea, then drifted to Long Hai beach. Buried by fishermen, the young girl repaid by helping fishermen go to sea to fish smoothly.
Fishermen also owe thanks to the Co's assistance and worship it more and more solemnly. Over the years, worship has become a festival as it is today. Unlike many coastal fishermen who worship Ca Ong, coastal fishermen in Long Hai worship Co, considering Co as a guardian god in the sea, also called Co Long Hai Than Nu.

According to Long Hai Commune People's Committee, Dinh Co Festival in Long Hai is not only a community cultural activity imbued with identity, but also affirms the sustainable vitality of the cultural heritage and unique folk beliefs of the Southern coastal region.
