Many Chinese holidays involve lanterns. But Lantern Festival represents the epitome of this custom.

Lanterns are first brought out on the thirteenth day of the first lunar month. They are tested on the fourteenth, formally lit on the fifteenth, and taken down on the eighteenth.

The origins of Chinese lanterns reach back to the Stone Age. The coming of the Bronze Age saw the development of various kinds of worked metal lanterns, of which palace lanterns were the most ornate. Later, decorative lanterns came to be used in festivals. Various lantern festivals became quite popular during the Sui Dynasty, and during the Southern Song Dynasty, the custom of writing riddles on lanterns emerged. During this time, a festival in Qinhuaihe in Nanjing featured over 10,000 lanterns. During the Qing Dynasty, magnificent exhibitions of lanterns were held in the capital city. Lantern contests were also held, with the dragon lantern being the most famous competitor.

Beijing also had a famous lantern market, while southern China was known for shows of lanterns on rivers and lakes. Ningxiang County in Shanxi Province was known for its "Mountain Festival of Lights," during which the mountainside was covered with a festive display of 10,000 lanterns. These festivals not only provided a beautiful show of multicolored lanterns, but also featured a wide range of folk art and performances, such as the Lion Dance, Dragon Lantern Dance, stilt-walking, land-boat racing, and Yangge dancing.
