In ancient times, window opening had many meanings in architectural design. Some palaces and ancient houses are designed with indoor air circulation and pollutant discharge in mind. Therefore, in these ancient buildings, windows are designed in appropriate positions and directions to introduce fresh air into the room and provide a good living environment. At the same time, the size and shape of the window also conform to the feng shui regulations to bring the best fortune and gas field.
The influence of geomantic omen still exists in modern design. In many modern buildings, window opening is considered as an important design feature, which can not only provide good ventilation conditions, but also optimize the indoor gas field from the perspective of geomantic omen. For example, from the perspective of geomantic omen, the bedroom window should not face the toilet, otherwise it will bring bad influence to the family. Similarly, the height and size of windows should be coordinated with other elements in the house to achieve the best feng shui effect.
