There is an alley not far from my window, with an open space in the middle. Someone has hung a Feng Shui mirror at the end of the alley, facing my window along the alley.

Feng Shui cannot be looked at in isolation. It needs to be discussed as a whole in conjunction with a person's Five Elements Numerology. For example, if someone lives in an auspicious house, they will be able to get promoted and make a fortune, and they will have good luck. On the other hand, some people are on the contrary. They lose their official positions and their relationships are fruitless. This is because the Feng Shui of a place always has the prosperity and decline of the five elements. Some five elements are very strong and some are very weak. If the five elements that are flourishing are the five elements that the homeowner likes to use, then he will live in good luck; if the five elements that are flourishing are the five elements that the homeowner is taboo about, then he will live in great misfortune.

When you open the window now, you will see a Feng Shui mirror, and something unpleasant happens after more than a month of living there, so it is still taboo. It is recommended that you adjust the Feng Shui of the room and hang a mirror on the window (you can use a professional Bagua mirror or a convex mirror) to reflect the "evil energy" coming from the opposite side.
