In 2010, Changsha Institute of Cultural Relics and Archeology excavated about 7,000 pieces of Eastern Han Dynasty bamboo slips. This finding filled in the blank of the unearthed literature in this period. In order to study the conservation status of bamboo slips and establish a scientific and reasonable cultural relic protection program, A number of Jane 牍 samples, carried out moisture content, shrinkage, cellulose crystallinity, surface color detection and material identification. The results showed that the cellulose of Jianxiong was severely degraded; the water content was high and the deterioration was serious; the oxidation of the surface was dark brown or even black; the wood was made of Chinese fir and the bamboo was bamboo.
