I put a palm-sized mirror on the doorframe opposite the door. I think something is wrong. What's your opinion?

In geomantic omen, the mirror has the function of reflection, so when the door is affected by suffocation, the mirror will be hung on the door to reflect suffocation. However, if there are people living across the street, the reflected Sha Qi will probably have a negative impact on neighbors, so we should communicate with each other so as not to hurt harmony.
