Why is a good day when everything is suitable called "auspicious day of the ecliptic"

from ancient times to now, people always like to choose a good day for weddings, sacrifices, funerals, business opening, building houses, etc., and pray for good luck and avoiding evil, that is, to choose a "auspicious day" to handle it. It is also recorded in ancient books, such as the fourth fold of the serial stratagem by an anonymous person in the Yuan Dynasty: "Today is an auspicious day of the ecliptic, and all the ministers of the Manchu Dynasty are at Yintaimen." The 18th Story of Heroes of Children: "Today is an auspicious day. Please ask a boy to bring my half-shouldered luggage in before opening the museum." Then, why is a good day when everything is suitable called "auspicious day in the ecliptic"? The ecliptic is an astronomical term, which refers to the orbit formed by the earth revolving around the sun and observing the relative movement of the sun and the earth from the earth. For example, "Han Tian Wen Zhi" records: "There is a middle way in the day and nine lines in the month. The middle path, the ecliptic, is a light path. " It means that the sun moves in the middle way and the moon has nine orbits. The middle path is the ecliptic, also known as the light path. In the Song Dynasty, the book Mengxi Bi Tan Xiang Shu Er was also included: "The cause of the sun is called the ecliptic." It means that the way the sun moves is called the ecliptic. In the ancient traditional calendar, there were days recorded by cadres and branches. In addition, some astrologers will take twelve places as branches, and match them with twelve gods on duty with different names, and make the underworld day, the zodiac as the master and the gangster as the master. During the twelfth day, the twelve gods took turns in sequence, and the cycle continued. Such as Ziri Qinglong, Ugly Ri Mingtang, Yin Ri Tianxun, Mao Ri Suzaku, Chen Ri Jingui, Si Ri Tiande, Noon White Tiger, Wei Ri Yutang, Shen Ri Tianlong, You Ri Xuanwu, Xu Ri Si Ming, Hai Ri Gou Chen. The twelve gods have different masters, and they are divided into good and bad. When the six gods, Qinglong (Zi), Mingtang (Ugly), Jingui (Chen), Tiande (Si), Yutang (Wei) and Siming (Xu), are on duty, it is an auspicious day, and everything is suitable, so people often say "auspicious day" and "ecliptic day". Qinglong is an auspicious beast handed down by God and a symbol of good fortune. Mingtang is the place where ancient emperors held ceremonies and a symbol of power. The golden chamber is a golden cabinet, which usually hides important cultural relics and documents, and is a rare symbol; Tiande is a symbol of the grace of heaven's education; Yutang is the palace, the residence of immortals, and the name of the star and the name of the god are all auspicious symbols. On the other hand, if the six gods, Heavenly Punishment (Yin), Suzaku (Mao), White Tiger (Noon), Heavenly Prison (Shen), Xuanwu (You) and Gouchen (Hai), are on duty, it is a bad day, and everything is unfavorable, so it is not appropriate to hold any major activities, which is called "Mafia Bad Day" and "Mafia Day". Mafia was originally one of the orbits of the sun and the moon. The ancients believed that the sun and the moon had nine orbits, namely, the ecliptic, the green, the equator, the white and the underworld. In addition, the ancient yin and yang scholars also regarded the underworld as an evil spirit, which is a symbol of bad luck. For example, Xie Zhaozhe's Five Miscellaneous Things, Tianbu II in the Ming Dynasty uploaded: "In one day, there are white tigers, black killers, knives and anvil, skyfire, heavy mourning, thieves, blood branches, blood taboos, returning taboos, underworld and other evil spirits." The ancients liked to pay attention to the weather, geographical location and human harmony, and all three were prepared to achieve great things. Choose the right "auspicious day", then you can occupy the most favorable opportunity of "the right time".
