The festival follows the lunar calendar and falls at a time when Mr Moon (Ong Giang) is most often spherical and bright. Homes are decorated with star-shaped lanterns and feature paper figures of laureate scholars and fruit displays of starfruit, persimmons and pomegranates with the addition of fragrant green rice (com).

Parents search out small treats for their children and tell the story of the immortal fairy Chi Hang, the white rabbit called Tho Trang and the buffalo boy Chu Cuoi who lives under the banyan tree on the moon. They often take their children to parks and supermarkets to buy toys, masks, lanterns and seasonal fruit.
