What should I pay attention to in Feng Shui on the bedroom window sill?

The window is the feng shui eye of the house. The top of the window must be higher than the height of the occupant, which depends on the height of the occupant, which can enhance the self-confidence and tolerance of the occupant, and the occupant does not need to bend over and arch his back when overlooking the scenery outside the window. In addition, air and sunshine are essential factors for human survival. If people breathe stale air for a long time, or are in an environment with insufficient light, they are prone to illness or depression. However, the bigger the window, the better. We must pay attention to the convection of air in the house, that is to say, the windows should be facing each other. For example, open a window facing north or facing east and west, so that the air in the house can circulate and the residents can be healthy.
