Snakes in Chinese mythology

Snakes (also known as serpents) are an important motif in Chinese mythology. There are various myths, legends, and folk tales about snakes. Chinese mythology refers to these and other myths found in the historical geographic area(s) of China. These myths include Chinese and other languages, as transmitted by Han Chinese as well as other ethnic groups (of which fifty-six are officially recognized by the current administration of China).

Snakes often appear in myth, religion, legend, or tales as fantastic beings unlike any possible real snake, often having a mix of snake with other body parts, such as having a human head, or magical abilities, such as shape-shifting. One famous snake that was able to transform back and forth between a snake and a human being was Madam White Snake in the Legend of the White Snake.

Other snakes or snake-like beings sometimes include deities, such as Fuxi and Nüwa and Gong Gong. Sometimes, Fuxi and Nuwa are described as snakes with human heads and sometimes as humans with dragon or serpent tails.

Myth versus history
In the study of historical Chinese culture, many of the stories that have been told regarding characters and events which have been written or told of the distant past have a double tradition: one tradition which presents a more historicized and one which presents a more mythological version.

River deities
In ancient China, some of the river gods which were worshiped were depicted in the form of some sort of snake or snake-like being:

Directional deities of the north
In the ancient China of the Han dynasty (206 BCE – 220 CE), worship of Four Directional deities developed, the directions were east, south, west, and north. With the direction of the middle, there were five major directions, each associated with a divine being or beings, a season, and a color (with the "middle direction" being associated with the emperor and the color yellow). This set of correlations of five whatevers included many more than mentioned here, in the elaborated philosophical system of Wǔ Xíng (五行), although some of the basics related to directional deities was much older.

The north was associated with a pair of divine beings, the Dark Warrior (Xuán Wǔ, 玄武), a tortoise-and-snake creature, with the season of winter, and with the color black (also often considered to be a deepish shade of blue). Each of the directions was also associated with one of the wǔ xíng, or five "elements" (sometimes also translated as "phases" or "materials"): that of the north was water.

According to Anthony Christie, the tortoise-and-snake combination was known as the Black Warrior. And, that although the worship of the other directions was an ancient practice, the worship of the north was usually avoided because the north was considered the dwelling place of a destructive deity of the ocean wind. However, the worship of the north was practiced, with sacrificial ceremonies to the Black Warrior, by the rulers of the Han dynasty, which claimed to rule with the protection of water and the north. Although the Black Warrior is generally depicted as a snake entwining around a turtle, sometimes, they are viewed as two separable generals.

Deities from snake
Bai Suzhen and Xiaoqing became deities from snakes.

Culture
In Chinese culture, mythologized snakes and snake-like beings have various roles, including the calendar system, poetry, and literature.

Zodiacal snake
In Chinese culture, years of the Snake are sixth in the cycle, following the Dragon Years, and recur every twelfth year. The Chinese New Year does not fall on a specific date, so it is essential to check the calendar to find the exact date on which each Snake Year actually begins. Snake years include: 1905, 1917, 1929, 1941, 1953, 1965, 1977, 1989, 2001, 2013, and 2025. The 12 "zodiacal" (that is, yearly) animals recur in a cycle of sixty years, with each animal occurring five times within the 60-year cycle, but with different aspects each of those 5 times. Thus, 2013 is a year of the yin water Snake, and actually starts on February 10, 2013 and lasts through January 30, 2014. The previous year of the yin water Snake was 1953.

In Thai culture, the year of the Snake is instead the year of the little Snake, and the year of the Dragon is the year of the big Snake.

According to one mythical legend, there is a reason for the order of the 12 animals in the 12-year cycle. The story goes that a race was held to cross a great river, and the order of the animals in the cycle was based upon their order in finishing the race. In this story, the Snake compensated for not being the best swimmer by hitching a hidden ride on the Horse's hoof, and when the Horse was just about to cross the finish line, jumping out, scaring the Horse, and thus edging it out for sixth place.

The same 12 animals are also used to symbolize the cycle of hours in the day, each being associated with a two-hour time period. The "hour" of the Snake is 9:00 to 11:00 a.m., the time when the sun warms up the earth, and Snakes slither out of their holes.

The reason the animal signs are referred to as "zodiacal" is because a person's personality is said to be influenced by the animal sign(s) ruling the time of birth, together with elemental aspect of that animal sign within the sexegenary (60 year) cycle. Similarly, the year governed by a particular animal sign is supposed to be characterized by it, with the effects particularly strong for people who were born in a year governed by the same animal sign.

Characters
The usual and general Chinese word and character for Snake is shé. As a zodiacal sign, the Snake is associated with, a proper noun referring to the 6th of the 12 Earthly Branches, or to the double-hour of 9-00-11:00 a.m.

The Five Noxious Creatures
On the fifth day of the fifth month of the Chinese calendar is the festival of the Double Fifth (Duanwu). Many of the activities traditional on this holiday involve expelling various sources of potential evil influences. One of these involves driving away the Five Noxious Creatures (wu du), of which the Snake is one.

Real and legendary
Some reports of fantastic snakes may belong more properly to the field of cryptozoology, legend, or folktale, rather than mythology or religion.

An example of this, is the "sudden striker" snake of Sunzi's Art of War that was supposed to be able to fight with both head and tail, and was used as a simile for how a general who is expert at military deployment does so. The Sudden Striker snake supposedly lived on "Mount Ch'ang": (Roger T. Ames believes this to have been Mount Heng, but written with a different character to avoid a naming taboo on the given name of Han Wendi).

Other snake-like or reptilian creatures
Other members of certain types of Chinese dragon are considered especially snake-like, such as the Teng, which is sometimes known as the "flying snake-dragon". Some reptilians are not at all snake-like, such as the Ao.
