Ying Yang Design Keyring is available in wide range. The ubiquitous yin-yang symbol holds its roots in Taoism/Daoism, a Chinese religion and philosophy. The yin, the dark swirl, is associated with shadows, femininity, and the trough of a wave; the yang, the light swirl, represents brightness, passion and growth. This symbol represents the perfect balance of the positive and negative energies. It is the Chinese perspective of balance and continual change. Since the circle is whole, therefore the two halves cannot be complete without the other. Order online and get Keyring at Wholesale Price.
