The Lantern Festival falls on the 15th day of the first month of the Chinese lunar calendar. People usually hang colorful lanterns, play riddle games and express their wishes and hopes for the future. At the Lantern Festival in Lin'an City during the Southern Song Dynasty, which is currently Hangzhou, 40 Li (20 km) of lights were lit. This spectacle was vividly depicted in ancient records such as Wulin Jiushi and Mengliang Lu.
