Boat racing and a wax castle procession are also included in the festival.
The event was said to have carried down from several generations as a means to worship Lord Buddha who, according to Buddhist legend, returned to earth
At this time, in the middle of the Mekong River, lights in various shapes from the floating boats can be seen from a long distance and this is considered as a significant symbol to uphold Buddhism. The event brings about happiness to all Buddhists while foreign visitors will enjoy watching a marvelous illuminated display.
