What is the knowledge of room airflow?

According to the annual fortune, which side is angry now? Gas stations are in the northeast, south, northwest and west. These four doors are angry ports. If it is in the southwest, in the east, in the north and in the southwest, then it is bound to be a mistake of yin and yang to sail in these four directions. Originally suitable for sitting on the mountain and watching the tigers fight, the opening of the air port is a mistake of yin and yang. According to feng shui theory, this is the dragon god going into the water and the water god going up the mountain.

The second thing is to distinguish between yin and yang. If you sit on a mountain for yin, you must open the Yang gate, and if you sit on a mountain for yang, you must open the Yin gate. For example, if I sit in a man's position here, I will open a woman's door. If I sit in a woman's position, I will open a man's door. This is the reason why a woman meets a woman and a woman meets a man, that is, in Feng Shui theory, yang comes from yin and yin comes from yang. In Feng Shui, Yin and Yang and Qi are very important knowledge.
