This is a Bat Amulet with a coin with the symbol of Pakua on one side and twelve Chinese horoscope animals on the other side.
In traditional China, the bat is a popular auspicious symbol of good luck and wealth because the sound for Bats in Chinese, ‘Fuk’ is similar to good fortune and happiness. During the days of the Manchu emperors, bats were the most popular symbol after the dragon being embroidered in imperial robes for high-ranking officials and the emperor. The designs were usually combined with another symbol of longevity such as cranes to connote long life and happiness.
You can hang this item anywhere in your house or office, or in the car to invite good fortune and wealth to everyone no matter what your horoscope sign is as well as to deflect negative energies.
