What does feng shui mean that the refrigerator door can't face the outside? Is the balcony outside?

Simply put, the place where natural light comes in is collectively called "outside". Besides, it doesn't matter if the door is facing, as long as it is hidden enough. For example, the refrigerator is placed in the kitchen, the door is 4 meters away from the rear window, and the north balcony is behind the window. This is no problem. Therefore, it cannot be simply understood that the refrigerator door cannot face outwards, and it is best to put the refrigerator in a sheltered position. As long as it's not too exposed, it's okay.
