According to Chinese mythology, a Nian is a beast that lives under the sea or in the mountains. The character nian more usually means "year" or "new year". The earliest written sources that refer to the nian as a creature date to early 20th century. As a result, it is unclear whether the Nian creature is an authentic part of traditional folk mythology or a part of a local oral tradition which was recorded in the early 20th century. Nian is one of the key characters in the Chinese New Year with scholars citing it as the reason behind several practices during the celebration such as wearing red clothing and creating noise from drums and fireworks.
Modern legends
Once every year at the beginning of Chinese New Year, the nian comes out of its hiding place to feed, mostly on men and animals. During winter, since food is sparse, he would go tothe village. He would eat the crops and sometimes the villagers, mostly children. There are several accounts as to how it looked, such as the way some sources cited that it resembles a flat-face lion with a dog's body and prominent incisor. Other authors described it as larger than an elephant with two long horns and many sharp teeth. The weaknesses of the nian are purported to be a sensitivity to loud noises, fire, and a fear of the color red. Some local legends attribute the Chinese lion dance to the legend of the nian. The tradition has its origins in a story of a nian's attack on a village. After the attack, the villagers discussed how to make the nian leave them in peace. Since it was discovered that the beast was afraid of the color red, people would put red lanterns and spring scrolls on their windows and doors. They would also leave food at their doorstep in a bid to divert it from eating humans. The traditions of firecrackers, red lanterns, and red robes found in many lion dance portrayals originate from the plan the villagers had in which drums, plates and empty bowls were hit, red robes were worn, and firecrackers were thrown, causing loud banging sounds that they hoped would intimidate the nian. According to this same myth, it was captured by Hongjun Laozu, an ancient Taoist monk, and became his mount.
Ancient sources
Various aspects of cultural practices relating to Chinese New Year are now included as part of the nian legend. These cultural practices are recorded in ancient texts, though none of them refer to a creature called nian. The Erya records that the character nian was first used to mean the year during the Zhou dynasty, replacing the different terms used in previous eras. The Shuowen Jiezi records that the character nian meant "ripeness of grains" and was composed of the character "he" and "qian" and quotes the Chunqiu which uses it in the sense of a great harvest. The attributes of the nian creature in the modern legend, of fear of noise and fire, correlates with ancient legends relating to the use of firecrackers to drive off ape-like creatures in the mountains called shanxiao, first recorded in the Shanhaijing. The practice of sweeping and cleaning at the start of the year is recorded in Zhou dynasty sources as intended to ward off plague spirits and the practice of using music and drama to receive gods and ward off plague spirits is also recorded from the same era. The creature's role in the celebration of the Chinese New Year is highlighted by the way the Chinese call this holiday Guo Nian, which means "pass over nian" or "overcome nian."
