How to solve the feng shui defect of office without windows

There is no window in the office, which means that the yang is not concentrated, and the yin is easy to knot, which will make people feel irritable, and those with yin deficiency are more virtual. Scientifically speaking, it is useless not to ventilate. Sunlight is easy to breed bacteria, which is not good for your health. Your suggestion is to put a landscape painting or photo on your desk where you can always see the "bright sun". Conditional offices should hang or post large pictures about the sun or fire in the south (far away from the fire), and try not to put water-related items such as fish tanks or drinking fountains in the north (Kanshui).
