It is not entirely sure when the idea of celebrating Chinese New Year first started, but ancient Chinese texts such as Master Lü’s Spring and Autumn Annals and Simin Yueling reveal that very early versions of these rituals could have begun as far back as the Han Dynasty or even the Warring States era.
According to folklore, people were once terrorised by a mythical beast called the Nian, who would appear during the time of the new year and make off with villagers. One year, an old man volunteered to stay and keep watch through the night while the villagers hid. He set off fireworks during his long wait, and when the village survived unscathed in the morning, people realised that the Nian disliked the colour red and loud noises. This is why every Chinese New Year, people started to put up red decorations, wear red clothes, light firecrackers, and bang on drums – all to frighten the Nian and keep it away.
