First of all, it is not advisable to choose rooms with beveled edges or polygonal shapes as bedrooms. Hypotenous edges can easily cause visual illusions, and polygonal houses can easily create a feeling of oppression, thus increasing people's mental burden. This is especially true for people whose zodiac signs have cooperative main stars (Taiyin, Tianliang, and Tiantong). What's more, such people are relatively weak and are prone to illness or accidents after being oppressed for a long time.
Secondly, avoid placing the bed too close to the window, and remember to keep the head of the bed against the wall. This is more important for people whose Ziwei natal charts are pioneering stars (Qi Sha, Po Jun, Lian Zhen, Greedy Wolf). A pioneering personality is more passionate and prone to taking risks. And if the bed is next to a window, it will make you feel empty and helpless, and you will not be able to keep your feet on the ground, which is very detrimental to the development of your career. Similarly, placing the head of your bed against the wall is also to give you something to rest on, enhance your luck as a noble person, and prevent you from fighting alone. At the same time, housing in modern metropolises often has buildings next to each other, and the bed is too close to the window, which will make your private life invisible.
