民间传说：古时，有怪兽名曰“年”，形若狮子而独角。定时出现伤害人畜，人们苦无制服之法。一次，“年”闯入某村，巧遇穿红衣，燃竹竿取暖者，“噼啪”爆炸有声，红光闪耀，“年”惊窜奔逃。于是人们认识“年”性，每逢“年”出时，家家户户闭门家居，贴红联，燃爆竹以驱“年”。“年”果不再来。人们庆幸过了“年关”，敲锣打鼓，互称“恭喜”，从此有了“过年”，也就是现在的春节。

According to tales and legends, the beginning of Chinese New Year started with the fight against a mythical beast called the Nian.Nian would come on the first day of New Year to eat livestock, crops, and even villagers, especially children. To protect themselves, the villagers would put food in front of their doors at the beginning of every year. It was believed that after the Nian ate the food they prepared, it wouldn’t attack any more people. One time, people saw that the Nian was scared away by a little child wearing red.
The villagers then understood that the Nian was afraid of the color red. Hence, every time when the New Year was about to come, the villagers would hang red lanterns and red spring scrolls on windows and doors. People also used firecrackers to frighten away the Nian. From then on, Nian never came to the village again. The Nian was eventually captured by Hongjun Laozu, an ancient Taoist monk. The Nian became Hongjun Laozu's mount.
