What does it mean that Feng Shui has violated the fate of children and mothers?

The master-slave door is a special double-door door, which consists of a smaller door leaf (sub-door) and a larger door leaf (mother door). Generally, when the width of the door opening is large, for the overall beauty of the door, the door leaf is designed in the form of large mother and child. Its safety is sufficient, and the double airtightness is treated by embedding soundproof airtightness strips inside and outside the door frame. The door frame and door leaf are made of rust-proof steel plate and baked at high temperature. The inner and outer door leaves are integrated structure, and there are no seam marks. The thickness of the inner and outer door leaves (sides) is about 5 cm. The door leaf is equipped with sound insulation structure, which can be customized, with a variety of door colors, sizes and locks, which is convenient for decoration. The external doors are all designed with an integrated anti-pry plate and five anti-pry buttons, which improves the safety level.
