In Chinese culture, it is thought that placing three or eight coins tied together with a red thread in your purse, taped onto your invoice book or on your cash register is one of the most effective ways to attract money and revenues into your life. The idea of "lucky coins" originates from ancient times when coins were worn as amulets or protection against disease, evil or negative energy directed at the wearer. They can be used in Feng Shui to represent prosperity and wealth or for I Ching (the ancient Chinese oracle).
