Travel notes were a kind of historical work and prose. This literary form originated from the Han and Wei dynasty, popular from the Six and Sui Tang dynasty to Ming and Qing dynasty. Many authors and varieties emerged in a period of more than a thousand years. In the initial stage of Han and Wei dynasty, the basic study about this form is rather poor. As a result, we do not know how many types or forms existed in this period or how it was done. We must gain a clear idea of the similarities and differences of travel notes. This thesis will answer those questions. According to their content, we differentiate between three types: foreign country notes, route notes and diplomatic travels, each with its own feature and writing technique. According to fashion, we classify those works into two kinds: travel biographies and travel notes. We will draw a clear distinction between two types on the following passage and discuss their basic writing features and patterns of evolution.
