Is the entrance door lower than the indoor door?

As the door of the family, the entrance door should be the tallest in the whole house. This is because the entrance door has an important symbolic significance in Feng Shui, representing the import and export of the family, which is related to the family's fortune and energy flow. If the entrance door is lower than the indoor door, it will not only be visually uncoordinated, but also lead to the negative impact of feng shui fortune.
