Twenty-eight stars, a great creation of ancient astronomy in China, continuously passed through the southern transit? The stars are divided into 28 groups, and each group is named after a word: horn, sound, surname, room, heart, tail, dustpan, bucket, cow, female, deficiency, danger, room, wall, tower, stomach, ang, bi, tapir, ginseng, well, ghost, willow, star and Zhang. Twenty-eight stars are divided along the ecliptic and equator; Since ancient times, people have set 24 solar terms according to the appearance of the four seasons and the transit.
The ancients divided the twenty-eight parts into four star regions, named them: Oriental Dragon, Northern Xuanwu, Western White Tiger and Southern Suzaku, and each star region had seven nights. Twenty-eight constellations revolve around the atmospheric surface of celestial bodies, holding the celestial phenomena in the east, west, north and south directions respectively, with the change of day and night, with the change of yin and number. However, in ancient geomantic omen, the twenty-eight constellations were divided into four directions, namely, Zuo Qinglong, You Baihu, Thousand-legged zaku and Houxuanwu.
The four images in the Book of Changes are Lao Yang, Laoyin, Shaoyang and Shaoyin, and the four images in Feng Shui are "Zuo Qinglong, Right White Tiger, Former Suzaku and Later Xuanwu". Confucian classics say that "Fu Xuanwu Gongbei, Suzaku South, Qinglong Pandong, and White Tiger Gathering West, the four potentials should be in all directions, and the acupoints are in the middle. If you get soft gas, you will be lucky, and if you get it, you will be fierce." The location of these four images is the geographical location of Feng Shui. Front, back, left and right are all balanced, harmonious, supple and prosperous, and only in this way can we have a good geography.
For the so-called left green dragon, right white tiger, former Suzaku, and later Xuan fighters, this is sitting north to south; If you sit south to north, on the contrary, it is left white tiger and right dragon, before Xuanwu and after Suzaku; Because dragon belongs to oriental wood, white tiger belongs to western gold, Xuanwu water in the north and Suzaku fire in the south, this is certain. It's just a habit that artists always open their mouths at the left Qinglong and the right White Tiger, regardless of the east, west and north.
In ancient times, in order to observe the movements of the sun, the moon and the five planets (gold, wood, water, fire and earth), people chose 28 constellations near the ecliptic and the equator as symbols, collectively called 28 constellations or 28 stars, and named them "Jiao, Kang, Shi, Fang, Xin, Wei and Ji" (these seven stars make up the image of a dragon, at the vernal equinox. Bucket, ox, female, emptiness, danger, house and wall [these seven stars form the image of a group of turtles and snakes interwoven and appear in the northern sky at the vernal equinox], so it is called "seven nights in northern Xuanwu, chief, building, stomach, pride, finish, mouth and ginseng [these seven stars form the image of a tiger and appear in the western sky at the vernal equinox]. An animal image composed of the above seven nights is collectively called the four elephants.
[Four dimensions, four beasts; The ancients used the appearance and arrival times of the four elephants and the twenty-eight constellations to determine the key methods of seasons. The five elements of the twenty-eight constellations, the tools used by modern Feng Shui masters, were determined from here. From the above data, it can be proved that the 28 constellations are the changes of the five elements in a year, rather than the usage of the 28 solar terms used in the modern peasant calendar. The ancients resigned themselves to their fate and looked at the solar terms in the south, so there were left oriental dragons, right western white tigers and post-oriental tigers.
Tai Chi is the noumenon, and the two instruments are yin and yang, which are called "Zuo Qinglong" and "Right White Tiger" in Kanyu, and the four elephants are called "Zuo Qinglong, Right White Tiger, Former Suzaku and Later Xuanwu" in Kanyu. Generally speaking, it is wrong to call dragon and tiger, but it is synonymous with left and right, and there is no such thing as "dragon" and "tiger". Secular theories, such as: the dragon side drains water, the tiger side can't open the door, and the toilet can't be installed. This is nonsense and wrong. As for the dragon face representing boys, it represents the tiger face of girls; It is also incorrect to say that the left side is higher than the right side, because of the ancient mentality of worshipping Yang and restraining Yin. In short, regardless of the yin and yang family, the balance between left and right is always good, the door can be opened or closed, and it is also possible to stand in different directions according to its gas situation. There is no need to be superstitious about dragons and tigers.
