The classics, full of wisdom, appeared as readable contexts by the way of languages, characters, or some specific expression. Nowadays, "Reading Classics" is one of those courses in general curriculum. The "Book of Changes", one of the most important Chinese traditional classics, contained the regulations of what happened in the world. It used unique expressions to record what the writer observed. However, that's the reason why it was uneasy to read. In this study, we offered three dimensions of reading and observing the "Book of Changes" as the level of methodology. The first, catching the true meaning of those terms. The second, realizing the symbolic meanings of images. The third, distinguishing the viewpoints between writer and reader. We sincerely hope those dimensions could point the practical methods to read the "Book of Changes", and expect readers could convert the knowledge and experience as their own wisdom.
