Lu Banchi is the most commonly used house to control the size of doors, so it is also called Menmi.
Lu half a foot, with a total length of 50.4 cm, is divided into eight squares, which are in turn wealth, illness, divorce, righteousness, official, robbery, harm and capital. Wealth, righteousness, official and capital are auspicious, and illness, divorce, robbery and harm are evil. Each cell is 6.3 cm, and each cell is divided into four cells, and each cell is marked with different good or bad words. The size of Jidu also has different uses. For example, Yimen is mainly used in schools, and closing doors is mainly used in government offices and officials. The words "Ben" and "Cai" are commonly used by ordinary people.
Nine-day Xuan Nv ruler is mainly used to control the size of indoor furniture, statues and ancestral tablets. Feet are 46.8 cm long.
A large number of practical examples prove that the size of the door does have an important impact on the villa. The reason can be explained as follows: the villa takes the door as the air outlet and receives the outside air through it, which may be "angry" that is beneficial to people's physical and mental health, or "sick" or unlucky that is harmful to people's physical and mental health. The key is the size of the air outlet, and the right air outlet can bring "anger" into the house. Explained by modern science and technology theory, the door is similar to a microwave resonant cavity. Doors of different sizes have different resonance effects on microwaves of different bands, and microwaves of different bands have different effects on people's physiological functions and mental activities. This is very similar to the principle that the length of radio antenna has different reception effects for different radio bands.
In ancient times, it was emphasized that the dark room in the bright hall and the windows were generally small, so the door was used as the air inlet, regardless of the air intake in the window. Some windows in modern layered houses are larger than doors, but the main entrance and exit doors are not often opened, so we should not only pay attention to the size of doors, but also consider the air intake function of windows (especially floor-to-ceiling windows). For doors and windows that are often opened, the size should be controlled so that the height and width of doors and windows (both refer to clearance) are controlled within the size of Kyrgyzstan.
