The merchant opposite my shop made a few words with LED. Because it is directly opposite, it is particularly dazzling. Does anyone know that it has an influence on my home in Feng Shui?

LED lamps are inherently dazzling. According to the truth, if you are a little public-minded, the words on the door should be milky white, and you should not use a transparent cover. This will affect others, but there is nothing in Feng Shui. I suggest you complain about him, or suggest that his book is not replaced with a milky white cover.
