Abstract:
Gemen Shi was first setup in the Tang Dynasty. And it was responsible for serving at court audiences, collecting memorials being submitted, presenting princes, prime ministers, foreign envoys and officials at the audience. In the Tang Dynasty, the function of Gemen Shi was taken over by palace eunuchs. Therefore, Gemen Shi was one of the various palace commissioners（内诸司使） during the Tang and Five Dynasties. However, it became one of the military ranks in the Song Dynasty.The system of Ruge（入閤） had a profound impact on the official ranks in the following dynasties such as Song, Liao, Jin, and Ming. Gemen Shi also can be found in their official systems.
