In the latitude and longitude of our country, the sun does not shine in the north for a long time, because the latitude and longitude of our country will shine in the south for a long time, because the sun can shine in the south all day, only before 12 in the east and after 2 pm in the west. There is basically no sun in the north or the distance is very small.
The direction of the living room balcony is the main direction, and the opposite of the main direction is the secondary direction. If the secondary direction has windows or balconies, it is bidirectional. For example, the balcony of the living room is difficult to copy, the opposite window or balcony is north-south, and so are other directions.
But which direction is better depends on personal preference. For example, some people don't need to be too hot to face north, and some people like to face south or west in the sun, so no direction is good, only which direction they like.
