If you believe in Feng Shui, the mirror facing the dining table certainly does not meet the installation requirements of the mirror in Feng Shui. Mirrors are indispensable in home decoration, but they are also recognized as "things that gather shadows" in Feng Shui. They are restricted in home decoration, and their installation is also particular, such as not facing the bed, doors and windows, writing desk and dining table.
I hope my answer can help you.
