The main activity associated with the Thai Yi Peng Lantern Festival is the release of lanterns into the sky. Participants create beautiful paper lanterns, often inscribed with wishes, and release them in large numbers, illuminating the night sky. This ceremony symbolizes letting go of misfortunes and inviting good luck and blessings. The festival, celebrated alongside Loi Krathong, prominently features floating lotus-shaped vessels on water, further emphasizing the theme of renewal and hope. The spectacular sight of lanterns soaring into the sky creates a poignant and magical atmosphere.
