We Chinese believe that taiji is the origin of all lives on Earth. Taiji comprises yin and yang, two types of vital energy. The five elements of wood, fire, earth, metal and water derive from yin and yang. These five elements correspond to, or affect, particular human organs. That is, the element of the fire corresponds to the heart, the wood to the liver, the earth to the spleen and the stomach, the metal to the lung and the water to the kidney. The combination of yin and yang gives birth to all lives on Earth. Taiji represents the harmonious state of balance between yin and yang. For a long time, the rest of the world was only aware of China's four major inventions: the compass, gunpowder, paper-making and movable-type printing.
Very few know about China's discovery of jingluo that exists in a human body. Jingluo is a system of internal main and collateral channels, regarded as a network of energy passages, along which acupuncture points are distributed. The existence of jingluo has been proved by using modern scientific methods at the Beijing Jingluo Research Center. The discovery of the existence of jingluo provides a strong support for the theories advanced in The Book of Changes and Huang Di's Classic of Internal Medicine.
