Please tell me, master, is my bedroom feng shui bad? How to correct it?

The environment that ignores Feng Shui is dangerous, and words and deeds that ignore Feng Shui are superficial!

From what you have said, it seems that the windows in your home are too big or too many, and the area occupied by the glass is too large. Not only do you feel insecure, but your subconscious mind is often in a state of tension. Moreover, it can easily lead to loss of energy and loss of vitality. This will lead to a bad mood, confusion at work and study, and many dissatisfactions will inevitably follow. You said it feels bad to have your back to the door. You should believe your feeling. This feeling is objective. The most basic thing in Feng Shui is to feel smooth. If you always feel awkward, how can you concentrate on work and study?

The information you provided is too abstract and far from sufficient. Curtains can be installed on the windows. For other aspects, you'd better ask a gentleman who knows Feng Shui to help you find out how to adjust them. If there is a problem in one link, a vicious cycle will easily occur. It should be taken seriously.
