 In ancient times, the lanterns were fairly simple, and only the emperor and noblemen had large ornate ones.
 In modern times, lanterns have been embellished with many complex designs.
 For example, lanterns are now often made in the shape of animals. The lanterns can symbolize the people letting go of their past selves and getting new ones,
Which they will let go of the next year. The lanterns are almost always red to symbolize good fortune.

 Lantern Festivals have also become popular in Western countries, such as the Water Lantern Festival held in multiple locations in the United States. In London, the Magical Lantern Festival is held annually.
