Please refer to:
The living room should be well ventilated and sunny.
The essence of this requirement is that at least one external wall of the living room should be equipped with a direct window, which can not only ventilate, but also directly communicate with the external natural environment to collect the brilliance of the sun and the moon. The window can't be too small, too small can't convey meaning; But it can't be too big, too big is suspected of air leakage. The total window area should be about a quarter to a sixth of the living room area. It's best that Japanese and China always have instant sunshine to shine on the Tai Chi point of the whole house. This means that the whole house and all family members can enjoy the sunshine, and the spirit must be positive and abundant.
Although some living rooms also have windows, there is a corridor outside the window, which not only can't see the outside landscape, but also greatly reduces the lighting. Moreover, the corridor is a place where others can walk and stay at will. It is said that every family has a difficult experience, and everyone has a difficult experience. If you open a window in the corridor, there is a danger that the wall will have ears, and there is a fear of peeping through the window, which will make the people in the living room feel depressed and affect the family fortune. What's more, the living room is big and square, but there is no window to collect natural light. The windows are all occupied by other rooms, and the living room can only be illuminated by decorative lights and glass doors in other rooms. This is not only a taboo in geomantic omen, but also a great failure in architectural design, which can be seen from time to time in old I-shaped buildings and buildings without patios.
