I have surveyed the Korean scholarship on pre-Qin history for last two decades. Only about thirteen scholars have produced their Ph.D. dissertations covering various topics in the field. Despite the limited quantity, the quality of the scholarship seems to have reached a certain level.BR Nevertheless, I would like to propose some methodological problems we need to reconsider. First, noting the excessive utilization of archaeological materials all over China, we must be very careful for the illusion of the cultural unification since the Neolithic period. Second, easy pictographic interpretations of ancient scripts such as oracle bone inscriptions may mislead to an exaggerated historical understanding. Third, uncareful mixed quotations between transmitted and excavated texts may also depreciate the value of the research.
