On How to Adjust Historiography Set

An obvious lopsided problem exists in the historiography set. Among the eight secondary disciplines of historiography, five are 'pure' Chinese history and one in other secondary disciplines, among which is one world history and one in others. Yet the land area of the world historiography is 15 times, the population is 4 times and the area of sea and ocean is 120 times as much as that in Chinese historiography. To solve this problem, two sets are suggested.1) Set up three first-class disciplines: Chinese history, foreign history and archaeology-museumology, 2) Build four secondary disciplines of historiography: ancient Chinese history, modern and contemporary Chinese history, the world history and archaeology-museumology.
