The head of the bed should be on the west side. This is the most appropriate way to place it in your current environment. Using the elimination method to explain this problem, it is definitely not good to put the head of the bed on the south side. There is no reason to put the head of the bed next to the window. From a Feng Shui perspective, it is not good to put the head of the bed next to the toilet. It is even worse if the head of the bed is placed on the east wall. First, when you enter the door and see the head of the bed, it is not good for privacy and is taboo. Second, the head of the bed faces the west. Feng Shui says that the head of the bed cannot face the west (that is, what you said means returning to the west). From this point of view, it is most appropriate for the head of the bed to be on the west wall. It avoids the toilet and window, and avoids seeing the head of the bed when you enter the door. It is also not the case that the head of the bed faces the west (it is okay if the head of the bed is on the west side, it faces the east). .
