The musical kites of Vietnam are a single, symmetrical wing, much like the Pechukan of Bali, equipped with sound-producing whistles. The dieu sao, musical kites, are also made in traditional forms like phoenix, dragons, and butterflies. In Vietnam, as in Thailand, Cambodia, and Laos, kites were typically flown by farmers in celebration of a successful harvest or to summon rain and good weather for their new planting.
