《 易经》最初有八卦，这个“卦”的意思就是挂起来的“挂”，也就是说你应该把它挂起来，然后经常看，就能参透其中的道理。这个和占卜是不一样的。你知道的占卜算命等说法，其实是后人将《易经》理论延伸后的产物。

Initially, the I Ching had the 8 trigrams. The meaning of this 'trigram' comes from the word, 'gua', or to hang up; meaning that you should first hang it up, examine it often, and then you will be able to fully understand the rationality within it. This is different than the practice of divination. The practice of divination and fortune telling that you know, are actually the products of later generations expanding on the theories of the I Ching.
