An analysis of the method of choosing a day for four days in seven houses.

Typically, folk vulgar teachers don't know astronomy and can't count stars, so they forged the Black Rabbit Classic, that is, the Black Rabbit Sun's Method of Choosing a Day, which is said to be the true tactic for Yang Gong to choose a day, and extracted the text of "Jiang Dahong's Tianyuan Song Black Rabbit Classic, leaving the world as a treasure ship" to show that it originated from the classic.

So what is the method of choosing a day for the black rabbit? Here is a brief introduction. As the rhyme goes, "Jiazi started in Kangong on the winter solstice, and started in beginning of spring on the vernal equinox. He followed Jiazi four times in the long summer, and stayed on the summer solstice to make a reversal. In beginning of autumn, Kun went against the autumnal equinox and made a winter retreat at work. In the end, we have to count nine stars from the star name, the earth, gold, jewelry, the sun and the moon. In case of the sun and the moon, Jin Muji and Tujero are the murderers. 」

An example of a song formula is as follows:

From the solstice of winter to the beginning of Chungen (that is, from the solstice of winter to the beginning of Chungen Jiazi), the vernal equinox earthquake was unfavorable to Jiazi, and Xun Gong in long summer echoed it, and Jiazi also echoed it. ) summer out of the palace, upstream, (from summer, Jiazi backwards), beginning of autumn Kun inverse autumnal equinox, beginning of winter kept.

Nine modes of ancient music in China

Do six ← beginning of winter anti-seven ← autumnal equinox gen eight → beginning of spring nine ← summer solstice.

Secondary five

Training Division ← Long Summer Earthquake III ← Vernal Equinox Kun II → Take a look at beginning of autumn ← Winter.

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

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

Its 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, Jia is in Kanyi, Yi is ugly in Kunyi, Bing Yin is in Zhensan, Ding Mao is in Xunsi, Chen Wu is in Zhongwu, Keith is in Liu Gan, Gengwu is piling up, Xin Wei is in Genba, Ren Shen is in Li Jiu, Gui You is in Kanyi, Jia Xu is in Kuner, and Yi Hai is in Xunsi. From the fifth in Ding Chou, from the nine planets. That is, Saturn, Venus to Liu Gan, Jetstar to Right 7, Luohougenba, Luoxing to Linjiu, (the sun is the sun) to Kanyi, and the lunar calendar is the lunar calendar) to Kuner, all of which are earthquakes, and Jupiter to Xunsi. That is, the sun of the Sun Rabbit goes to Renzikan, the Moon goes to Shen Kun, Venus goes to the sea, and Jupiter goes to Chen Xun. Therefore, Kan Kun Can built a tomb, four hexagrams and twelve mountains.

Another example is Ding Chou, which was built on the eighth day of August in Jiazi year. It is found that after the autumnal equinox, Jiazi went retrograde from Dugong (due to the yin retrograde from summer to early winter), that is, Jiazi converted from Qijiawu, from Yihai to Zhongwu, from Bingzi to Xunsi, and from Ding Chou to Zhensan. In the earthquake, three Saturn retrograde, depending on the sun, the moon and Jin Mu's four auspicious stars. Choose a suitable one.

The inheritor praised: "The Five Pictures Classic selected in this article has been observed for a long time since it was discovered by Yang Gong, and it was praised by Tianyuan and Wusong Dynasties at the stage of Zhengzheng Fair in Ming Dynasty. However, I saw Qingjiangzi who slandered Jing Qing. He was a black rabbit, and he intercepted nine Obidians from eleven Obidians, which turned upside down and violated the principle of heaven, seven houses and four surpluses. He really doesn't know that this Nine Obsidian is different from Jingwei Seven Administration. Hey! He thinks he knows his family like the back of his hand, but he thinks that Yang Gong is a true biography, but he doesn't know that Yang Gong is an article, and there are profound truths of Yi learning that Qingjiangzi can't see! "

The original author said: "He thinks he knows his family like the back of his hand. He thinks it's a true biography of Yang Gong, but he doesn't know that Yang Gong is an article. He has a philosophy of easy learning. I can see what Qingjiangzi can see! " I want to position the Black Rabbit Classic as the true biography of Yang Gong in an understatement. I know that in the Selected Works of Yang Gong's Yi Long Jing, it is clearly stated that Sunday is the 11th Obsidian, and I only suspect that it is the 11th Obsidian, not the 9th Obsidian. Qingjiangzi, the great master of Qing Dynasty, 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 have always taken the words out of context, misinterpreted the original text, and did not understand the truth and truth, but faked trademarks, referring to deer as horses, but unexpectedly matched the truth and falsehood. So this statement should be like this: "Yang Gong's method of nature is really astronomical, easy to learn, and rabbits can't choose a day!"

Strictly speaking, the black rabbit's method of choosing a day is a false pretence of later generations. It is not Yang Gong's method of "looking up to the sky on Sunday", nor is it the category of Jiang Gonghun Tianbao taking care of the seven-day star. Qingjiangzi is right. The method of choosing the day in the Five Maps is different from that in the Seven Houses and Four Reserved Stars.

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

Secondly, the Seven Houses and Four Rest Stars choose their dates according to the latitude and longitude of each place and the time of use, and judge good or bad luck by the angle of the mountain direction, the life palace and the formation of each star, but the rabbit sun is not; Choosing a day after the seven-day break is an astronomical knowledge, which is complicated and difficult to master. You need a teacher to teach you, but Utsune doesn't.

Moreover, it is a rigid dogma that the black rabbit grandson will always be a lucky star when he chooses a day, and a bad star will always be a bad star; However, the good or ill luck of a star in choosing a day is always determined, 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's solar day selection method is not the actual astronomical astrology, because the operation of actual stars is slow and slow, and Wutu's solar day 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. So its intersection point is called "node". After the festival, it gradually moved westward, and returned to its original place after 18.6 years, with an inclination angle of about 65448.6 years with the equator. In this way, the age difference causes the ball axis to make a small elliptical motion along the track, 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 lunar orbit will be opposite to the original direction, so the lunar 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 ascent point and perigee are not constants. It is quite complicated to calculate the perihelion angle first, then the position of the moon on the ecliptic, and then the latitude and longitude of the moon on the ecliptic. If we want to calculate the exact direction of the moon, the amount of calculation is very large, so we must use trigonometric function, 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 a genius and clever, and his juvenile understanding is abnormal. In 854, at the age of 20, he became a scholar in imperial academy. When he arrived in Tang Xizong, the official went to the imperial court, Dr. Lu Jinguang, a top official and director of Lingtai, was in charge of 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 in charge of astronomy in Lingtai. How could he not know how stars work? Yang Gong also made it very clear in the Selected Works of the Suspected Dragon Classic: "I test the sky because of the number of times, and the mysterious image is subtle; When the stars arrive at dawn, there is no time, only Wuyang will last forever. " . If you look at Song of Life carefully, you will know that brevity is not enough for those who don't know much about stars. And < < Wu Tu Jing >:< Meaning, the sages argued a lot, and those who knew it knew it at a glance, but this was a contempt for Ye Fu's ignorance.

To sum up, Yang Gong's Nature Law and Jiang Dahong & gt's fifth "Choice" talk about the selection of the stars in the Seven Dynasties, not the rabbits and grandchildren. It is nonsense to say that Yang Gong chose the right day, which is obvious.
