The Yee Peng Festival in Chiang Mai, Thailand, takes place on the full moon of the second month of the Buddhist Lanna calendar. Yee means “two” and Peng means “full moon day”.

In this festival, Khom Loi, Lanna style sky lanterns, are lighted and released into the air. The act of releasing the lantern symbolises letting go of the ills and misfortunes of the previous year. Thousands and thousands of lanterns can be witnessed throughout the night.
