Analysis on the selection methods of seven governments and four remaining days.

A typical folk layman doesn't know astronomy and can't count stars, so he forged the "Black Rabbit Sutra", that is, the method of choosing a day by the black rabbit sun, which is said to be the true tactic of Yang Gong's choosing a day, and extracted the words "Jiang Dahong sang the Black Rabbit Sutra in Tianyuan, and left it as a treasure raft" to show that it originated from the classics.

So what is the method of choosing a day for the black rabbit? Here is a brief introduction. For example, this poem says: "Jiazi rises in the Kangong Palace on the solstice in winter, and the vernal equinox rises at the beginning of spring. He follows Jiazi four times in long summer, leaving the summer solstice to set the reverse wheel. When he was in beginning of autumn, Kun went against the autumnal equinox and took a winter vacation at work. On the last day, we will count nine stars from the star name, the earth, gold, jewelry, the sun and the moon. As the sun flies, Jin Muji and Tujero are both murderers. 」

An example of a song formula is as follows:

From the solstice of winter to the beginning of spring (that is, from the solstice of winter to the beginning of Gengong Jiazi in spring), the vernal equinox earthquake is unfavorable to Jiazi, while Xun Gong in the long summer colluded with Jiazi and entered Xun Gong in the long summer, where Jiazi colluded with Jiazi. ) That summer, he went out of the palace and went upstream (from the solstice of summer, Jia went backwards). Kun of beginning of autumn went against the autumnal equinox, and Kun of beginning of winter went against beginning of winter.

Nine modes of ancient music in China

Dry six ← beginning of winter against seven ← autumnal equinox gen eight → beginning of spring against nine ← summer solstice.

Secondary five

Xunsi ← Long Summer Earthquake Saint ← Vernal Equinox Kuner → beginning of autumn Kanyu ← Winter Solstice.

Winter Solstice, beginning of spring, Vernal Equinox, Changxia, Shunjiazi, Summer Solstice, beginning of autumn, Autumnal Equinox, beginning of winter and Inverse Jiazi.

Earth, gold, wood, Romania, Mongolia, the sun, the moon, rice and water are pushed out of their houses (and solar terms)

The method is to divide it into winter and summer. If Ding Chou is used in daily work, it will be after the winter solstice, and then it will be pushed down from the ridge. That is, Jiazi is in the Kanyu, Yi Chou is in Kun Er, Bing Yin is in Zhen San, Ding Mao is in Xun Si, Chen Wu is in Zhongwu, Keith is in Liu Gan, Geng Wu is in DuiQi, Xin Wei is in Genba and Ren Shen is in. That is to say, Saturn, Venus to Liu Gan, Jetstar to Duihui 7, Luohou Genba, Luoxing to Linjiu, (the sun is the sun) to Kanyu, and the lunar calendar is the lunar calendar) to Kuner, all of which are counted as earthquakes, and Jupiter is thinking. Japanese rabbit's sun goes to Renzikan, Taiyin to Shen Kun, Venus to Ganhai, Jupiter to Chen Xun. Therefore, Kan Kun Can built a tomb and built four hexagrams and twelve mountains.

Another example is Ding Chou, built on the eighth day of August in Jiazi year. After investigation, Jiazi came from Duigong retrograde after the autumnal equinox (due to the yin retrograde from summer solstice to early winter), that is, Jiazi changed from Qijiawu to Zhongwu (pushing the truth), from Yihai to Xiangsi, and from Ding Chou to Zhensan. After the earthquake, Saturn went retrograde three times, depending on the position of Jin Mu's four auspicious stars. Choose a suitable one.

The inheritor said appreciatively, "This paper chose Wutujing, which has been observed for a long time since the discovery of Yang Gong, and has been praised since Tianyuan Wuge reached the fair stage of Chiang Kai-shek in the Ming Dynasty. But when I saw Qingjiangzi who slandered Jing Qing, his cloud was black, Rabbit Sun, and he intercepted 9 obsidians from 1 1 obsidians, which reversed and violated the principle of seven governments and four surpluses in heaven. He really doesn't know that this Nine Obsidian is different from Jingwei Seven Administration. Hey! He thinks he knows his family, but he thinks Yang Gong's true biography, but he doesn't know that Yang Gong is an article with profound principles of Yi-ology, which Qingjiangzi can't see! "

The original author said: "He thinks he knows the family like the back of his hand, but he thinks it is a true biography of Yang Gong, but he doesn't know that Yang Gong is an article, and he has a philosophy of easy learning. I can see what Qingjiangzi can see! " To put it simply, I want to position The Black Rabbit Classic as a true biography of Yang Gong. I know that Yang Gong's "Yi Long Jing" and "Selected Articles" make it very clear that Sunday is eleven obsidians, but I just doubt that it is eleven obsidians, not nine obsidians. Qing master Qingjiangzi kept his word. The black rabbit mentioned in Jiang Gong's Tianyuan Black Rabbit Classic Volume I refers to the sun and the jade rabbit, the sun and the moon. It can be seen that since ancient times, counterfeiters' usual methods have been taken out of context, misinterpreting the original text, not knowing the truth and the truth, but counterfeiting trademarks, referring to deer as horses, but unexpectedly confronting the truth and falsehood. Therefore, this statement should be like this: "Yang Gong's life method is really astronomical and easy to learn, so the rabbit can't choose a day!"

Strictly speaking, the black rabbit's method of choosing a day is a kind of false trust of later generations. It is not Yang Gong's method of "looking at the sky on Sunday", nor is it the category that Jiang Gong Huntianbao takes care of the stars for seven days. It is the right thing to clear Jiang Zi. The method of choosing the day in the afternoon map is different from the method of choosing the day in the seven houses and four prepared stars;

First of all, the date selection of the Seven Mansions and Four Wonders depends on the actual operation of the star, which is tangible. The nine planet days of the black rabbit sun are invisible and imaginary;

Secondly, the Seven Houses and the Four-Day Leisure Stars choose their days according to the latitude and longitude of each place and the time of use, and use the angle of the mountain direction, the life palace and the formation of each star to determine whether it is good or bad, but the rabbit sun is not; Choosing a day after seven days of government affairs and four days of rest is an astronomical science, which is complicated and difficult to master. You need a teacher to teach you, but Wu Tusun is not.

Moreover, the black rabbit sun will always be a lucky star when it chooses a day, and a bad star will always be a bad star, which is a rigid dogma; However, the good or ill luck of the stars is decided at any time, and the good or ill luck stars can be transformed into each other under certain conditions, which is in line with materialist dialectics.

The astrology arranged by Wutu solar date selection method is not the actual astronomical astrology, because the operation of actual stars is slow and slow, and Wutu solar date selection method is rigid and stagnant. The precession of the actual astronomical phenomena should also be considered. The calculation of the actual astronomical phenomena is not a dense calendar and cannot be accurately calculated.

Take the moon star as an example. The inclination of its orbit to the ecliptic is 5 degrees, and the inclination to the equator is between 19.5 degrees and 28.5 degrees. Therefore, its intersection point is called "node". After the node, it gradually moved westward, and returned to the original place after 18.6 years, with an inclination angle of about 65448.6 years with the equator. Therefore, the age difference causes the ball axis to move along the track in a small ellipse, which is about 9.2 seconds. The intersection of yellow and white recedes from the ecliptic for about 3 minutes, every day 1 1 sec, and the product is 67093.39 days, which is about 18.6 years. It is called orthogonality. When it runs for half a week, the direction of the moon's orbit will be opposite to the initial stage, so the monthly orbit will change every week. There are mainly solar movements, business trips, annual differences and monthly differences. Therefore, every step of calculating the real moon position needs to be corrected. Secondly, the lifting point and perigee are not constants. First calculate the perihelion angle, then calculate the position of the moon on the ecliptic, and then calculate the latitude and longitude of the moon on the ecliptic, which is quite complicated. If you want to calculate the exact direction of the moon, there are many calculations, and you must use trigonometric functions, preferably software.

Therefore, the orientation calculated by the seven-house star selection method and the black rabbit sun selection method is very different.

According to textual research, Yang Yi, whose real name is Yun Song, was born in 834 and died in 904. Yang Gong is gifted and clever, and his juvenile understanding is abnormal. In 854, at the age of 20, he became a scholar in imperial academy. In Tang Xizong, the official went to the imperial court. He was a third-grade official and director of the Lingtai, responsible for the planning and layout of palace buildings and important temples, as well as astronomical observation and royal sacrifices. Imagine that astronomy was developed in the Han and Tang Dynasties, and Yang Gong was a great scholar who was in charge of astronomy in GV. How can he not know the principle of star operation? Yang Gong also made it very clear in the Selected Works of the Suspected Dragon Classic: "Because I have many times, I have tested the heavens, and the mystery is subtle; When the stars come at dawn, there is no time, only Wuyang will last forever. " . If you read the "Song of Creating Life" carefully, you will know that it is concise and clear, which is not enough for those who don't know the stars deeply. And The Five Classics:> means that the sages have argued a lot, and those who know it will know it as soon as they see it, but it is a contempt for Ye Fu's ignorance.

To sum up, Yang Gong's life law and Jiang Dahong & gt's fifth song "Choice" are about choosing the date by the stars in the seventh political period, not by the rabbit sun. Obviously, it is nonsense to say that Yang Gong chose the right day.
