上古时期，黄河中游的河洛地区出现了两幅神图——河图与洛书。
It is said that in the pre-ancient times, He Tu and Luo Shu appeared in He Luo area around the Yellow River.
河图满载黑点与白点，玄机暗藏；洛书由纵、横、斜三条线上的数字组成，其和总是等于15，奇妙异常。
He Tu is a picture full of black and white dots which embodies endless mysteries and and Luo Shu is a picture consists of numbers of vertical, horizontal and oblique lines whose sum is always 15, which is truly wonderful.
伏羲就此演绎出八卦。几千年后，文王被暴君周王囚禁在羑里，在此期间，他又将八卦进一步推演发展为六十四卦，这些卦经一代又一代流传下来，统称为《周易》。
The King Fu Xi deducted and developed the Eight Trigrams. Thousands years later, the King Wen was incarcerated in You Li by the tyrant King Zhou and during that time he further deducted and developed the Eight Trigrams to the Sixty-four Hexagrams which were passed generation after generation whose names are called the The Book of Changecollectively.
