The auspicious day of the ecliptic is well-founded and reasonable.

In the past, astrology was used to calculate good luck and bad luck. It is said that the six stars of Qinglong, Tang Ming, Jingui, Tiande, Yutang and Siming are auspicious gods. When these six stars are on duty, they are called "auspicious days".

The so-called ecliptic, China ancients thought that the sun goes around the earth, and the ecliptic is the imaginary orbit of the sun around the earth. "Tian Han Wen Zhi" records: "There is a middle way in the day and nine lines in the month. The middle road, the ecliptic, is the light road. " There are twelve constellations with the highest brightness in the ecliptic sky, namely Qinglong, Baihu, Tang Ming, Tianxun, Suzaku, Jingui, Tiande, Yutang, Tianlong, Xuanwu, Siming and Gouchen.

The ancients believed that choosing the auspicious day of the ecliptic is not good or bad regardless of the year, month and time, but depends on each other and makes a comprehensive choice. The six immortals, such as White Tiger, Natural Punishment, Suzaku, Tianlong, Xuanwu and Gouchen, are regarded as evil spirits, and it is considered that misfortune will lead to great disaster. Qinglong, Tang Ming, Jingui, Tiande, Yutang and Siming are collectively called the six zodiac signs. The so-called auspicious day of the zodiac is the day when these six gods are located.

The day when the Six Gods are on duty is called the auspicious day of the ecliptic, and everything goes smoothly without avoiding evil spirits. For example, Yuan Anonymous's "The Series of Rings" is the fourth fold: "Today is an auspicious day for the Emperor's Road, and all the ministers of the Manchu Dynasty are at Yintai Gate, urging the Taishi to enter the DPRK to give meditation." Although this statement is suspected of superstition, it has pinned the good wishes of the ancient people in China to avoid misfortune. The ecliptic sometimes refers to the path taken by the son of heaven. For example, in Song Dynasty's Notes on Old Learning Temple (Volume 7): "When the high temple was stationed in Lin 'an, it was difficult to travel, and every time it went out, it was called the ecliptic. Take three guards. "
