Apart from bringing abundant good fortune, these special gold coins can also provide powerful protection as amulets. These protective coins combine two potent symbols of protection: the 8 Trigrams of the Pa Kua and a Taoist Mantra. Hang them behind you at work to ensure protection and support for your business. Place above the front door of your home or attach to the inside doorknob to protect your family from harmful influences outside the home. The side with the 8 trigrams should be placed flat against the door or wall while the side with the taoist mantra should face you.
