People float their Krathongs in Surin, Thailand, Nov. 22, 2018. Thailand observed the annual Loy Krathong festival on Thursday. As a tradition that has been followed for at least seven centuries, people set afloat lotus-shaped rafts adorned with candles, incense and flowers, known as Krathongs, around the twelfth full moon night of the Thai calendar while wishing a year's bad luck to be washed away by the waters.
