Best Answer - Chosen by Asker:

This picture is of the YIN - YANG symbol.
This symbol only exists in Chinese culture.
It stands for the duality of nature.
YIN is the female. YANG is the male.
In every female there is a little male. Female is passive.
In every male there is a little female. Male is active.
Notice the small dot inside the larger half circle?
It has been used by the native Philosophy/Religion of China called Taoism, or Daoism. This is NOT superstition.
