For many people, especially non-East Asian, the Chinese language is quite difficult, due to the excessive differences between it and their native ones. In practice, nearly every language has its hard side, on which we should lay stress; and its easy side, of which we could take advantage.

对于不少人（特别是东亚地区以外的人）来说，汉语是门相当难学的语言，因为它跟自己的母语差异甚多。实际上，几乎每种语言都有其困难的一面和简单的一面，我们需要着重加强对困难部分的把握，而简单的部分则会带来便利。
