The materials of Taihang Mountain documents collected by Handan College are analyzed by Hertz Berg staining and the results show that the materials include bast fibre, straw fiber, bamboo fiber and wood fiber. Some materials are made up of two or more fibers.Through statistical analysis, it is found that folk archives tend to choose Chinese traditional bast fiber paper such as hemp paper and bark paper, while the choice of official documents is greatly influenced by the development trend of the paper industry.The above findings are helpful to expand the study of paper making history in Ming and Qing Dynasties and provide references for the restoration of folk archives.
