A Dragon Horse jumped out from the River before 3083 B.C. in China. Fu Xi found a weird diagram on the horseback. The diagram shows 5 and 10 marks in the center, 3 and 8 marks on the left, 4 and 9 marks on the right; 2 and 7 marks on the top, and 1 and 6 marks on the bottom. That implied every group of two numbers can get along well together. This diagram is called the "River Diagram".

Chinese Five Elements, Metal, Water, Wood, Fire, and Earth are used by Chinese astrology. They can be broken down into Yin and Yang as ten Heavenly Stems. The sequence of ten Heavenly Stems is Yang Wood, Yin Wood, Yang Fire, Yin Fire, Yang Earth, Yin Earth, Yang Water, and Yin Water 
. Using the numerology of the River Diagram, we find ten Heavenly Stems can have five groups in a romantic relationship. The stems in the same group attract each other.

Five Elements have a connection with four seasons and four directions. Wood is connected to spring and the East. Fire is connected to summer and the South. Earth is connected to the center and in-between seasons. Metal is connected to autumn and the West. Water is connected to the winter and the North.
