Most of the inscriptions on the vernacular tablets of the Yuan Dynasty are translated from the Mongolian language of the Yuan Dynasty, which is a valuable original historical material. The value of the vernacular monument of the Yuan Dynasty can be explained from both linguistics and history. The first is linguistic value. Most of the various gongmu of the Yuan Dynasty were first written in Mongolian and then translated into Chinese vernacular. Although this vernacular, due to the limitation of translation level, cannot be completely consistent with the actual Chinese at that time, it still reflects the colloquial vernacular situation of the Yuan Dynasty to a certain extent, and has become a good material for studying the history of Chinese in the Yuan Dynasty. This book is a compilation of such materials.
