Abstract
In order to make the research different from the traditional way in political system study of early medieval China，this book discusses the administrative system，administrative documents of marquis state Linxiang（临湘侯国，equivalent to a county）and its operation，with the help of Zoumalou（走马楼）Sun-Wu slips unearthed from Changsha（长沙）.
As the bamboo and wooden slips being disturbed when unearthed，first of all，this book deals with restoration and edition of them，including classifying documents written on wooden tablets，and restoring scattered bamboo slips into volumes.On the basis of these work，the author attempts to reconstruct the original appearance of official documents in Sun-Wu Slips.
Related research consists of the following 3 topics.Firstly，by collecting information provided by official documents，using the method of personal name integration of Yuan（掾）（a general term of office worker），this book resolves the disputes over the nature and administrative level of Sun-Wu slips，identifies them as marquis state Linxiang's documents.
Secondly，the author studies on the operation mechanism of official documents of Linxiang county.Cao（曹）（secretarial departments）is responsible for document production and operation，whilst menxia（门下）（the secretary institution of the county head）should be the unified sender of official documents.This is the source of the documentary operating mechanism of the Six Dynasties
Thirdly，the scattered bamboo and wooden slips contains information on a judicial case that an office worker Xu Di（许迪）stole a large number of rice belonging to the local authorities.The author attempts to reveal the judicial procedure of this case and thereupon，discuss a county's daily judicial affairs and their operation.
Twenty-five years after the discovery of Zoumalou Slips，this book，as an advanced research monograph on the Three Kingdoms era，is also of great significance in the conservation，restoration and research of cultural relics unearthed in Changsha and Hunan（湖南）.
