"Compared with traditional ancient book restoration, the current process is more scientific and standardized," Wu said. "The establishment of restoration records is also more standardized. We refer to modern restoration standards for cultural relics. It's systematic."

"Ancient book restoration plays a significant role in the protection and inheritance of our Chinese culture," restorer Chen Qian said.

"Through restoration and preservation, the life-span of these precious ancient books is extended, providing important materials for future generations to use in study and research. Ancient books are important sources that a nation can use to build cultural confidence. Restored ancient books can also help the world understand the long history and culture of China."
