Can I put Pixiu on the corner of the window?
Generally speaking, this kind of Feng Shui evil is called Dao evil. To resolve sword evil, one usually uses a flat Bagua mirror or a convex Bagua mirror to face the evil position. You can also place a lighted dragon facing the evil position to eliminate evil spirits.
You now use Pixiu. In Feng Shui, Pixiu has the function of fighting against the five yellow evils and transforming the three evil spirits (the calamity evil, the calamity evil, and the old evil), so it can be placed in places where the evil spirits are relatively heavy to transform the evil spirits.
In Feng Shui, dragon, unicorn and Pixiu have similar Feng Shui effects, but they are not exactly the same. First of all, the attribute of dragon is water, and some Pixiu belong to water and some belong to fire. Logically speaking, what you do now should be able to resolve the evil spirits. But the chosen Pixiu should not be the kind that attracts wealth, but should be the one that brings home security. It is not a lying one, but a standing lion-like overlord Pixiu, and it is best to have one foot raised forward to form a dragon's claw shape. This kind of Pixiu is the one used to control the house and transform evil spirits. Only this kind of brave man can transform this evil spirit. To turn evil spirits away, the more ferocious the Pixiu looks, the better. This type of Overlord Pixiu is the most effective.
The most important thing is that the Pixiu you use must be consecrated, and it must be consecrated by a Taoist priest or monk. Only this kind of Pixiu can play a role in Feng Shui. Otherwise, it is just an ornament and has no effect.
