The balcony of my hall is facing the corner of the hotel opposite. How to solve it?

Although feudal superstition is not credible, Feng Shui still has an influence. Because it has an impact on your mind, as you said, it is a negative impact. This sharp corner, like a knife, always gives you psychological pressure, which is a great murderer. Suggestion: You'd better change your residence. If not, at least use a large potted plant or something to block it. Don't see this sharp corner at a glance. Try to make it fade out of your life.
