On the one hand, according to Feng Shui theory, the front door is Yang and the back door is Yin. Frequent back door entry may aggravate Yin Qi and have a negative impact on the fortune of family members. Therefore, family members are encouraged to use the front door more and the back door less.
On the other hand, if the back door is locked, it is necessary to open the door lock every time you go in and out, which also increases the trouble and risk. If you often go through the back door, you may forget to lock it because of negligence, which may lead to hidden dangers in family safety.
Generally speaking, it is suggested to make the most appropriate decision according to the actual situation and demand and considering all factors comprehensively. At the same time, we should also pay attention to family safety, ensure the doors and windows are locked, and ensure the safety of our families.
