The Moon Lantern Festival or “Tet Trung Thu” is held on the fifteenth day of the eighth lunar month when the moon is round and brightest at this time of year. It was originally a harvest festival associated with the moon and is now celebrated for the youth and family. Traditionally, children make elaborate lanterns and moon masks with the adults and enjoy the moon cake. The holiday recounts the legend of Cuội, whose wife accidentally soiled on a sacred banyan tree, taking him with it to the Moon. Every year, on the moon festival, children light lanterns and participate in a procession to show Cuội the way to Earth.
