The paper records the entire process of arrangement and conservation of bamboo slips and wooden tablets excavated from Tomb M8 of Zhoujiazhai Cemetery in Suizhou, Hubei Province. To meet the requirements needed for character recognition and information acquisition, we designed the methods for arrangement and conservation of bamboo slips and wooden tablets. Our professionals divided all of the tomb goods—bamboo slips and wooden tablets covered by mud—into several categories and separated the bamboo slips and wooden tablets, which were badly deteriorated, then cleaned and decolorized the slips and tablets to their natural colors. In addition, we explored the working mode of scientific excavation and timely arrangement and synchronous conservation of waterlogged slips and tablets excavated from tombs in south China. This work provides some experience for the conservation of similar cultural relics in the future.
