Sitting facing south is not only for lighting, but also to avoid the north wind. The topography of China determines that its air is seasonal. There is a cold current in northwest Asia in winter, a cool breeze in the Pacific Ocean in summer, and the direction of monsoon changes all year round. There is a record of wind measurement in Oracle Bone Inscriptions. The Historical Records says: "Evil winds live in the northwest and arrive in October. The factory lives in the north, and it is also November. The wind lives in the northeast, and the first month is also. The Ming people lived in the east and in February. The Qingming wind lives in the southeast dimension, also in April. The scenery is in the south, and it is also May. The cool breeze lives in the southwest, and it is also June. Occasionally, the wind will live in the west, and in September.
In addition, sitting facing south is the best orientation for ancient palaces. As a home, when decorating, you can put a few coins under the door stone, or put a string of Jiuwudi money specially used for geomantic omen, or hang a string behind the door after decorating, and then put golden toad or brave ornaments in the living room, so that the wealth and people of this apartment are very prosperous.
