The bedroom door faces north and the window faces south. How to put feng shui on the bed is better?

In principle, the place to sleep should be backed by the mountain (gable) and facing the Feng Shui. That is to say, when people lie down, there is wind and water under their feet. The window is in the south and the door is in the north. If there is a through flow, be careful not to block it. What's more, sleeping at night and the cold wind blowing slowly are not good for the human body. What's more, you can use water to put things (small fish tanks, humidifiers, etc. ) before going to bed, this can also make the bedroom dry. In fact, there are some similarities between the Book of Changes and some modern concepts. A little experience, sir. Do you think so? ……
