Loy Krathong
Last nite, Damuan river were transformed into the Chao Phraya where the Thai community in Brunei gathered to celebrate the Loy Krathong (or Loi Kratong, Thai ลอยกระทง) under the full moon.
According to Wiki;
"Loi” means “to float”. “Krathong” is a raft about a handspan in diameter traditionally made from a section of banana tree trunk (although modern-day versions often use styrofoam), decorated with elaborately-folded banana leaves, flowers, candles, incense sticks etc. During the night of the full moon, many people will release a small raft like this on a river. Governmental offices, corporations and other organizations also build much bigger and more elaborate rafts, and these are often judged in contests. In addition, fireworks and beauty contests take place during the festival.
