Usually falling in February or early March on the Gregorian calendar, it marks the final day of the traditional Chinese New Year celebrations.[1] As early as the Western Han Dynasty (206 BCE-CE 25), it had become a festival with great significance.[2] During the Lantern Festival, children go out at night carrying paper lanterns and solve riddles on the lanterns (simplified Chinese: 猜灯谜; traditional Chinese: 猜燈謎; pinyin: cāidēngmí; Jyutping: caai1 dang1 mai4).[3][4]
