The civil service examination system was an important political, social and cultural mechanism in traditional China. The "Lists of chin-shih (the graduates of the metropolitan examinations)" (chin-shih-lu) published immediately after each examination have been considered invaluable sources in the study of the early moderm Chinese history. While sixteen examinations were held during the Yuan dynasty (1260-1368), only the lists of two are still extant. This paper is one part of the results of author's reconstruction of all Yuan chin-shih lists and contains the lists of the chin-shih of the two earliest Yuban examinations (those of 1315 and 1318). The reconstruction has drawn widely from historical works, literary writings, collections of anecdotes, epigraphic materials, and local gazetteers. Out of the 106 chin-shihs conferred in these two examinations, the names and biographical data of 91 have been reconstructed, amounting to 85.8% of the total. The biographical data included in our reconstructed lists go much beyond those contained in the conventional chin-shih lists. In addition to chin-shih's names, registered places of residence, ages, spouses, the names and status of their lineal ancestors of the preceding three generations and their own initial appointment, we have included also in our list as far as possible, The data on chin-shih's educational backgrounds, official careers, published and unpublished writings, and the status of their collaterals, marital relatives and descendants. Hopefully, the additional data will enhance the value of our reconstructed lists in the study of the the political, social, and cultural history of early modem China.
