This art film is a paper-cut animation that tells the origin of "New Year's Eve" and "Nian." In ancient times, a monster named "Xi" would descend upon the human world on the evening of the thirtieth day of the twelfth lunar month, wreaking havoc among the people. Even the Kitchen God was powerless against it. Later, the Kitchen God ascended to heaven to seek help from the heavenly deities. The immortal child "Nian" volunteered to come to the mortal realm. Under the Kitchen God's skeptical gaze, "Nian" battled "Xi" for several rounds, ultimately defeating the monster with a bamboo pole and red silk. To celebrate this victory, the people named the thirtieth day of the twelfth lunar month "Chuxi" (the removal of Xi). In honor of "Nian's" achievement, they named the first day of the first lunar month "Guonian" (passing of Nian). These customs have been passed down to this day, though "burning bamboo poles" has evolved into "setting off firecrackers," and "hanging red silk" has become "pasting spring couplets."
