Chinese astrology was elaborated during the
Zhou dynasty (1046–256 BC) and flourished during the
Han dynasty (2nd century BC to 2nd century AD). During the Han period, the familiar elements of traditional Chinese culture—the yin-yang philosophy, the theory and technology of the five elements (
Wuxing), the concepts of heaven and earth, and Taoist, Buddhist and Confucian morality—were brought together to formalize the philosophical principles of Chinese medicine and divination, astrology and alchemy. The five
classical planets are associated with the
wuxing: •
Mars—
Fire (
Vermilion Bird) (may be associated with the phoenix which was also an imperial symbol along with the
Dragon) •
Mercury—
Water (
Black Tortoise) •
Jupiter—
Wood (
Azure Dragon) •
Venus—
Metal or Gold (
White Tiger) •
Saturn—
Earth or Soil (
Yellow Dragon) According to Chinese astrology, a person's fate can be determined by the position of the major planets at the person's birth along with the positions of the Sun, Moon, comets, the person's time of birth, and
zodiac sign. The system of the twelve-year cycle of animal signs was built from observations of the orbit of
Jupiter (the Year Star; ). Following the orbit of Jupiter around the Sun, Chinese astronomers divided the celestial circle into 12 sections, and rounded it to 12 years (from 11.86). Jupiter is associated with the constellation
Sheti (-
Boötes) and is sometimes called Sheti. A system of computing one's predestined fate is based on birthday, birth season, and birth hour, known as
zi wei dou shu (), or Purple Star Astrology, is still used regularly in modern-day Chinese astrology to divine one's fortune. The 28
Chinese constellations,
Xiu (), are quite different from Western constellations. For example, the Big Bear (
Ursa Major) is known as
Dou (); the belt of
Orion is known as
Shen (), or the "Happiness, Fortune, Longevity" trio of demigods. The seven northern constellations are referred to as
Xuan Wu (). Xuan Wu is also known as the spirit of the northern sky or the spirit of water in
Taoist belief. In addition to astrological readings of the heavenly bodies, the stars in the sky form the basis of many
fairy tales. For example, the
Summer Triangle is the trio of the cowherd (
Altair), the weaving maiden fairy (
Vega), and the "tai bai" fairy (
Deneb). The two forbidden lovers were separated by the silvery river (the
Milky Way). Each year on the seventh day of the seventh month in the Chinese calendar, the birds form a bridge across the Milky Way. The cowherd carries their two sons (the two stars on each side of
Altair) across the bridge to reunite with their fairy mother. The tai bai fairy acts as the chaperone of these two immortal lovers.
Chinese zodiac Chinese astrology has a close relation with Chinese philosophy. The core values and concepts of Chinese philosophy originate from Taoism. ==Table of the sixty-year calendar==
