Xuanwu is black, and the image is a snake wrapped around a turtle. The Journey to the West mentioned that it later evolved into the second general of Tortoise and Snake under the seat of Emperor Xuanwu in the north. Emperor Xuanwu's Dojo is in Wudang Mountain, Hubei Province, so Wuhan embraces Guishan and Sheshan across the river (also named after its shape).
Turtles and snakes were regarded as sacred animals in ancient China, symbolizing longevity. Before the Han Dynasty, nobles wore jade turtles, but now, influenced by ancient China, turtle patterns are widely used in naming and making emblems in Japan. However, China later misrepresented that the female turtle could not mate with the male turtle, but only with the snake. When the male turtle was very angry, the female turtle drew a circle with urine, and the male turtle could not get close, so it gradually evolved into calling the man whose wife was having an affair a turtle, which became a swearing word. Gradually, no one uses turtles to make patterns and names. There was Li Guinian in the Tang Dynasty, and the brothel handyman was called "tortoise" in the script of the Ming Dynasty. It is not clear whether the pattern of Xuanwu originated from the mating of snakes and turtles, but this pattern and symbolic significance may have appeared as early as the Zhou Dynasty, and perhaps the legend of the mating of snakes and turtles came from this pattern. Four images
Twenty-eight lodgings with four orientations are based on the morning and evening phenomena around the ancient vernal equinox. At this time, Zhu Bird lived in the south for seven nights, Black Dragon lived in the east for seven nights, Xuanwu lived in the north for seven nights, and White Tiger lived in the west for seven nights. The collocation of four colors is related to the ancient five elements theory. As for the origin of the collocation of dragons, turtles, snakes, tigers and birds, one view is that it is related to the totem of primitive tribes; There is also a theory that it may be related to the seasonal characteristics of these constellations when they are unconscious. For example, seven nights in the south are spring, and birds can be regarded as a symbol of spring and so on.
/kloc-in the summer of 0/978, an ancient tomb in the early years of the Warring States Period (dating back to the 5th century BC) was excavated in Sui County, Hubei Province, which contained a lacquer box cover with the name of 28 basu and the corresponding images of Qinglong and Baihu written on it. This not only advanced the time of the appearance of the twenty-eight lodges recorded in the literature, but also confirmed that the origin of the four elephants with twenty-eight lodges was also very early.
In the ancient literature of China, twenty-eight hotels were established, and some stars in the twenty-eight hotels appeared earlier. For example, in the Spring and Autumn Period (8th to 5th century BC), there were many books such as The Book of Songs and Xia.
Record. In addition, in the book Yao Dian, there are records of "four stars in the sky", that is, "the stars in the sun are birds in the sky with midsummer", "the sun is always sparking with midsummer", "the stars in the night are empty with Zhong Qiu" and "the sun is short and the stars are long with midsummer". So some people think that Twenty-eight Nights was born in this era. However, some people think that the appearance of a few star names does not prove that the 28 th guest house system was established at that time. The early reliable documents containing twenty-eight lodging houses include Lu's Spring and Autumn Annals, Book of Rites, Moon Order, Zhou Li and other books, and the earliest time was about the middle of the Warring States Period (4th century BC). Judging from the astronomical phenomena in these records, it can be advanced to the middle of the Spring and Autumn Period (the seventh century BC). The discovery of Erbasu lacquer box cover unearthed in Suixian County, Hubei Province advanced the documentary evidence to the fifth century BC.
Others believe that 28 hotels were distributed along the equator at the beginning of their establishment. Calculations show that the time when the Twenty-eight Hostels coincided with the celestial equator was about 5,000 years ago. This can be considered as the upper limit of the times when the 28 th Guest House system was founded. The fifth century BC confirmed by documents and cultural relics should be regarded as the lower limit of the founding era of the 28 th Hostel.
In ancient India and other countries, in addition to China, ancient India (including today's Pakistani and Bangladeshi), Arabia, Iran, Egypt and other countries also have a 28-night system similar to that of China. Because Iran, Arabia, Egypt and other countries appeared relatively late and have many similarities with the Twenty-eight Hostels in India, it is generally believed that the Twenty-eight Hostels in these areas were handed down from India in ancient times. Nack Satra (or Nachaat La). There are twenty-seven nights and twenty-eight nights. Twenty-seven huts appeared earlier, mainly twenty-seven huts, and then twenty-eight huts were added. 27 nights plus Abhijit (whose contact star is Vega) is 28 nights. The name of "Krittica" (the Pleiades star of China) is as follows: In the Twenty-Eight Hostels of India, each night also chooses a bright star as its representative, which is called the main sequence contact star (Yogatara). However, it can't function as a distant star in China on the 28th night. Each night is divided into 27 nights, with an average of 360 13 20', instead of the main star.
Regarding the origin of twenty-eight hostels, did it originate in China or India? There is no conclusion.
Shierchen
In ancient China, Sunday was divided into twelve parts from east to west along the celestial equator, and represented by twelve names in the square, namely, Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai. It has a certain correspondence with the constellations of 28 constellations (see Chapter 12). When the stars are in the south of the sky, there is a one-to-one correspondence between the twelve stars and the twelve branches of the earth square. /kloc-One of the applications for 0/2 years old is the year. There are different opinions about the original meaning of twelve Chen, and there is no conclusion yet.
Twelve times
In ancient China, in order to observe the position and movement of the sun, the moon and the five stars, the zodiac was divided into twelve sections from west to east, called twelve o'clock. The names of the twelve times are:,, (female),, building, girder, stone god, quail head, quail fire, quail tail, birthday girl, fire and wood analysis. These names have been recorded in Zuozhuan and Guoyu in the Spring and Autumn Period and the Warring States Period, which are used to describe the location of Muxing. In ancient times, Jupiter's constant week
It is set to twelve years, so it is generally believed that the twelve creations originated from the observation of Jupiter. It can be traced back to the Spring and Autumn Period or earlier. However, in Mandarin, Lingzhou dove (the astrologer of Wang Shi) said: "The king of Wu cut Yin and was older than the quail fire." According to China astronomer Yuzhe Zhang's research on the orbit of Halley's comet in recent years, it is believed that the attack time of King Wu should be 1057 BC. At that time, the old star was indeed in the second quail fire, so this statement of Lingzhou dove should be the actual observation at the beginning of the week. If this conclusion is reliable, it is also possible to push the founding era of the Twelve Dynasties to the end of Yin and the beginning of Zhou Dynasty.
Qian Baoyu, a Chinese historian of science, believes that the division of twelve times was originally based on twenty-eight houses and four palaces (that is, four elephants), with three times in each palace. Because the width of the right ascension across the four palaces is uneven, the width of the twelve right ascension is also uneven. But later it developed into a system of equal division according to equatorial degrees. The beginning and end of Han Law are twelve degrees, corresponding to twenty-four solar terms. Take the twelve solar terms as the starting point of each time and the twelve middle qi as the midpoint of each time. This division principle has been used until later. However, due to the influence of precession, the starting and ending degrees are gradually changing. After the end of the Ming Dynasty, twelve names were used to translate the zodiac, such as Capricorn Palace as Jixing Palace. However, the starting point of each palace was changed to correspond to the twelve meridians, and each palace was equally divided according to the longitude of the ecliptic. For example, the Jixing Palace at the starting point corresponds to the winter solstice, and so on.
