1. Ensure that the written book is smooth: the ancient books are different in damage degree, and the repair difficulty is different. It takes at least 3-5 days to ensure the smoothness of the pages when the ancient books are restored and exhibited.
2. Avoid secondary damage to ancient books: After rough repair, ancient books need to be flattened, and each ancient book needs to be flattened 15 to 20 days to ensure the smoothness of the pages.
