 Doing history also forces the historian to make choices about the scale of the history with which he or she is concerned. Suppose we are interested in Asian history. Are we concerned with Asia as a continent, including China, India, Cambodia, and Japan, or the whole of China during the Ming Dynasty, or Hubei Province? Or if we define our interest in terms of a single important historical event like the Chinese Revolution, are we concerned with the whole of the Chinese Revolution, the base area of Yenan, or the specific experience of a handful of villages in Shandong during the 1940s? Given the fundamental heterogeneity of social life, the choice of scale makes an important difference to the findings.
