China's ancient books were destroyed or even destroyed by natural and man-made disasters in history. Compared with the ancient books formed by the Chinese nation in the whole historical development process, the protection of ancient books is more important.
The principle of "protection first, rescue first, rational utilization and strengthening management" also applies to ancient books. However, due to poor preservation conditions, ancient books were damaged by insects, mildew, acidification and aging, and some even became "book bricks" that could not be turned over, or were seriously moth-eaten and flocculent ancient books. It has become an urgent task to do everything possible to protect and rescue ancient books and ensure their safety.
