What is the feng shui function of hanging Chinese knots at home?

There is also a kind of Chinese knot that is considered as a magical thing, which can achieve the effects of exorcising evil spirits, suppressing evil spirits and protecting yang from yin, such as "auspicious knot" and "winding knot". As an amulet embodying mysterious religious concepts, this knot is widely used among the people and has formed a certain inheritance mechanism. This is probably one of the reasons why the "knot" culture is endless.
