My office faces south and is rectangular in shape, with floor-to-ceiling windows behind it. What’s the feng shui like? What should I do if it’s not good?

When I looked at the picture, it was not a good direction. Having a floor-to-ceiling window behind is the biggest disadvantage. It is generally recommended to have a physical object behind it. This is what is called a backer. Besides, if you have a floor-to-ceiling window behind you, do you always feel like someone can come in at will from a psychological point of view? It is recommended that you change it.
