On the one hand, it may be more suitable for boys to live in the shade, because it is traditionally believed that the yang of boys is more important than that of girls, and a dark room may help to balance the yang of boys. On the other hand, girls may be more suitable to live in the sunshine, because sunshine is good for girls' health.
However, according to Feng Shui, the positive house is conducive to the growth and development of boys, while the negative house is conducive to the growth and development of girls. This is because the sun room is sunny and warm, which can promote the physical and mental development of boys; The shady room is cooler and good for the girl's health.
To sum up, the choice of boys and girls living in the sunny side and the shady side depends on personal needs and preferences, as well as geomantic considerations. However, it should be noted that no matter what kind of room you choose, you must ensure that the room has good lighting and ventilation, as well as suitable temperature and humidity to promote the healthy growth of children.
