Houses in the northern hemisphere all face south, so do houses in the southern hemisphere all face north?

yes. Because the sun rotates along the ecliptic, living in the northern hemisphere (top in the picture), the sun is in the south (bottom in the picture), and the house facing south faces the sun, and the north is backlit. Living in the northern hemisphere, the sun is in the north (above), which is naturally the opposite of the northern hemisphere. Only when you face the north (above) can you get sunlight.

Ancient people were superstitious that such a house design would help promote family fortune and accumulate happiness for the family. In fact, despite this superstition, it is also very reasonable for China people to design houses facing south, because China is in the northern hemisphere, and the house facing south is helpful for lighting inside the house and can avoid many problems.

Extended information:

The sitting orientation of a house is derived from the front and back orientation when people sit. When a person sits, the position of the spine is sitting, and the position of the front of the body is facing. In other words, the front is facing and the back is sitting. The "sitting" of the house is the azimuth of the rear end of the central axis of the longitudinal building on the ground plane, and the direction is the azimuth of the front end of this central axis. In geomantic omen,

twenty-four mountains are used to represent the sitting azimuth of the house. The sitting direction of the house is determined by the longitudinal building axis of the house. Generally speaking, the vertical line of the back wall of the house is sitting, and the other end of this vertical line is sitting. The sitting direction includes the sitting direction of the house and the sitting direction of the door. The sitting direction of the door and the house is the same, but there are also differences. For doors that are different from the orientation of the house, additional measurements should be made. ?
