Because the Lantern Festival night is the first full moon night, and based on the phychological association of the roundness of the full moon with the togetherness of the families, the representative celebratial food of the Lantern Festival is the rice balls, with its round shape (like the full moon) symbolizing the reunion of families and representing the joyful atmosphere of the Lunar New Year. The most special step in the traditinal rice balls manufacturing process is to shake the stuffings around in a great round shallow bamboo sieve full of glutinous rice powders to make the round shape of the rice balls.
