The mirror in the room cannot face the window. Because mirrors are yin and cold things, if the mirror is pointed at a window, it will cause the yin energy to collide. Heavy yin energy will attract uncleanness. There is often a folk saying that mirrors looking at windows attract ghosts. For this reason, mirrors have the function of reflecting light. Therefore, if the mirror is facing the window, there will be reflections, which will affect the home and fortune. It will also form reflections, and Feng Shui will not be able to enter, thus affecting the accumulation of wind and Qi, causing unnecessary conflicts.
