The Yin Yang Symbol is called Tai Chi Diagram in China. This is because
the Tai Chi philosophy is widely spread by I-Ching and Taoism.
There is no answer for who drew the first Tai Chi diagram. One says
Tai-Chi is all from Fu-Xi, who
invested I-Ching before Chinese written history. Yin Yang S-shape was
found on the pottery in Shiah Dynasty (2205 B.C.) and
Chou (1122 B.C.) Dynasty. Others say it came from Han
(104 B.C.) Dynasty, Tan Dynasty or Sung Dynasty. The
following is the first Tai Chi diagram found and is called
Old Tai-Chi Diagram.
