"Three Ming Tonghui·On General Star Canopy": "The canopy is like a precious canopy. There is this star in the sky. Its shape is like a canopy, and it always covers the throne of the emperor. Therefore, it is located at the three junctions to obtain the treasury. , called the canopy."
There are two meanings here. One is that the name of the canopy comes from astronomical observations. It is a star that "always covers the seat of the emperor" and is shaped like a canopy; The definition starts from the Three Combinations of the Five Elements, "it is called the canopy based on the three combinations." The so-called Deku, taking Muju as an example, is not the Muku, Haimao is not the day, it is the canopy when it is not seen, and so on.
Obviously, there is no logical relationship between astronomical observation and Sanhejianku. "Sanming Tonghui" only uses the word "gu" to connect the two together, so we can only regard it as an image borrowing. In other words, numerology borrows the Huagai Star to name the Sanhe Fengku, that's all. "Li Yuge" says: "There are few brothers among the canopy of stars, and the lonely place in the sky" is a borrowed description. People with the triple combination of Jianku often have a lonely, artistic, and monkish nature, which is just described in the name of being aloof and aloof.
The four pillars of Jianku, that is, Chenxu Chouwei, are just a record of time, not the entire definition of Huagai. Huagai is a relationship between the five elements, and the decision-making power lies in the location of the storehouse of the three combined forces. For example, if you are born on the Yin day, you will see Xu as a canopy. Because Yinwu and Xu are three combined fire bureaus, you will see Xu as a storehouse of fire. For people born on the Yinwu day of Xu, Xu will be a canopy. However, people born on the day of Mao will not use Xu as a canopy when they see the year of Xu, because Haimao has not yet combined the three wood positions, and Xu will not be used as a canopy. It can be proved from this that the Huagai is not a high and constant reference object that can be given to anyone in the world, but can be given to certain specific people according to the rules of the Five Elements and Three Harmonies. Therefore, behind the canopy are the five elements and the rules of numerology, not the stars.
It is really a mistake for later generations to understand Huagai as a divine evil and to make it mystical. The concept of Huagai is not explained by star destiny, but by the five elements and numerology. Huagai is just a borrowed image and name. However, numerology has not made a reasonable discussion on the aloof nature of Sanhe Jianku, which makes the relationship between the image borrowing of Huagai and the logic of numerology blurred. This is a subject that needs further research.
It is generally believed that the positive meaning of the canopy is art, the middle meaning is nobleness, and the negative meaning is loneliness. If it has a seal, it means you have a noble sign, which is the most auspicious.
