This is a full-length historical novel. Using famous figures of the Western Han as its threads and major historical events as its warp, the author recounts the dynasty's history from a fresh perspective in the form of a “train.” The book also draws lessons from the past for the present, in accessible and lively prose. Readers can board the Western Han train and glimpse momentous historical secrets amid flashing blades, then pause for reflection and savor the deeper meaning of history. It is an excellent introduction to Chinese history for middle and high school students, as well as history enthusiasts.
