At the end of ceremony, the martyrs' comrades wave goodbye to the flower wreath floating out to the sea.
Early March 14, 1988, the Vietnamese Navy’s Brigade 125 sent three ships with nearly 100 officers and soldiers to the Gac Ma (Johnson South), Co Lin (Collins or Johnson North) and Len Dao (Lansdowne) reefs in the Spratly Archipelago.
The soldiers were transporting construction materials on to Gac Ma when four Chinese vessels arrived and attacked them.
A total of 64 Vietnamese soldiers were killed in battle, and they are remembered as the Gac Ma soldiers.
