Science means the exploration of truth. In the process of exploring truth，people will have to experience tremendous hardships and difficulties before they can come to understand the objective laws. It is often the case that the differences in the research perspectives， the materials mastered， and the ways of understanding would lead to totally different results—as we might say，“a mountain becomes a hill when viewed horizontally and a peak when viewed vertically，and it assumes totally different shapes when viewed from a short or a long distance，or from a high or a low position.” – and even lead to academic disputes.
