When buying a house in Zhengzhou, what is the best orientation for the house?

Famous pavilions and elegant buildings in ancient times were often backed by green mountains and facing green water. They were considered by the people as "feng shui treasures". And there is indeed some scientific truth to this. The back (north) is surrounded by green mountains, which can block the biting cold wind in winter and welcome the cool south wind in summer; the gurgling stream in front provides necessary water sources; and the deep mountains and dense forests provide fresh air. Such a beautiful natural environment makes people living here feel relaxed and happy, and the solid rock foundation allows the buildings to last for hundreds of years without falling down. Our country's house habit of "facing north and facing south" also has its scientific reason. Our country is located in the northern hemisphere, and most of it is in the northern temperate zone. The sun mostly rises from east to south and sets from the west. In winter, the sun's altitude angle is smaller, and the doors and windows of the house face south, which allows more oblique sunlight to enter the room, thereby increasing the indoor temperature. In summer, when the sun's altitude angle increases, relatively less light enters through doors and windows, thus keeping the room cool. Furthermore, most of our country is located in the East Asian monsoon zone. Houses facing south can avoid the direct sunlight in the hottest afternoon in the midsummer, and can avoid the cold northwest wind in the midwinter, thus preventing cold and keeping warm. Anyway. The window must be in the south to get sunlight! The bed should be placed in the north-south direction, and it is better if the head of the bed is in the north!
