What does the constellation house mean?

Palace refers to the sky above and below the horizon-astronomers call the celestial sphere 12 part.

First, use the horizon to divide the heads of the first and seventh houses, or the rising point and the falling point-they correspond to the time of sunrise and sunset every day. Then there is the meridian connecting the mid-sky and the low-sky-representing noon and midnight of the day. Other palaces are subdivided between these two axes.

Think of the palace circle as a clock or a sundial. In fact, the astrolabe can be regarded as both a clock and a calendar, because the outer circle of the astrolabe (the zodiac) corresponds to the calendar of the four seasons. In astrology, the house represents the place where energy appears, so the house can show the background, field and situation.
