The chapters take the form of anecdotes meant to illustrate various strategies and tricks employed by the Warring States. With the focus thus being more on providing general political insights than on presenting the whole history of the period, there is no stringent year-by-year dating such as that found in the preceding Spring and Autumn Annals. Stories are sorted chronologically by under which ruler they take place, but within the reign of a single king there is no way to tell if the time elapsed between two anecdotes is a day or a year.
