There are strict requirements for the placement or hanging of Zhong Kui's portrait in Feng Shui. If you don't know how to hang it, it won't help, but it will be counterproductive. Zhong Kui's portrait must not be hung for himself, but must be hung externally, which can not only play a feng shui role, but also avoid the influence of Sha Qi.
Evil spirits or beasts, such as animals, should not be placed or hung towards themselves, otherwise it will be counterproductive. Moreover, in order to have the function of feng shui, it is necessary to go through the opening ceremony. Zhong Kui seems to have experienced the opening ceremony of Taoism. If you don't turn on the light, you will be invisible. "Form" is material, and "God" is verve, spirit and soul. Only having both form and spirit can play a feng shui role. Otherwise, the invisible god can only be an ordinary ornament, not a feng shui thing.
