Long-boat racing is one of the traditional rites which marks the end of the Buddhist Rains Retreat.
It mainly takes place in the 11th or 12th lunar months when the water level is at its highest.
Traditionally, long-boat racing is held as an annual event
At present, long-boat racing is considered as a national sport.
However, boat racing in those days was just a mean to keep boat men physically and mentally fit for national defense.
The festival event draws several hundreds of local and foreign spectators who watch the race along both sides of the riverbank enthusiastically.
