Liu Heng's geomantic interpretation of Ba Zhai: The good and bad luck of the nine planets should be timely, and the relationship between the five elements and the nine planets.

In the interpretation of Eight Houses in Liu Heng, the relationship between the nine planets and their lucky or unlucky periods and fleeting five elements is as follows: the lucky or unlucky period of the nine planets is divided into nine palaces, each with a main star and two auxiliary stars, with a total of 27 stars. According to the chart of flying stars in Jiugong, each family's main star, auxiliary star and their positions have different good and bad cycles. For example, the sick star is located in the southeast and the main star is the fourth star. When the fourth star comes, the sick star is a bad star, and vice versa. The relationship between the five elements of fleeting time and the nine planets The five elements of geomantic omen include gold, wood, water, fire and earth, which are closely related to the nine planets. In the fleeting time, the changes of the five elements will play an important role in the influence of the nine planets. For example, Venus is in charge of wealth, and the appearance of golden planets in a fleeting time will contribute to the promotion of wealth, and vice versa. In addition, different attributes of the five elements will have different effects on the nine planets. Generally speaking, the relationship between the good and bad times of the nine planets and the fleeting five elements and the nine planets in the geomantic interpretation of the eight houses in Liu Heng is very important, which can help people understand their own fortune and grasp the key of geomantic omen, thus achieving the effect of improving geomantic omen and enhancing fortune.
