The traditional event, known as a feast and commemoration festival for Hoang Sa Soldiers, pays tribute to the men enlisted in the flotilla to patrol the Hoang Sa and Truong Sa (Spratly), tap natural resources, and defend national island sovereignty. In 2013, it was accredited as a national intangible cultural heritage.  The ceremony has been observed over centuries by families in Ly Son and many coastal areas in Quang Ngai, attracting increasing participation from visitors across Vietnam in recent years. Following local tradition, after the ceremony, a boat race was held. In the past, such races were organised to select skillful and strong seafarers to join the flotilla./.
