At both ends of the "Maritime Silk Road" are two ancient libraries - Tianyi Pavilion in Ningbo, China, and Medici Lorenzo Library in Florence, Italy. After more than 400 years of wind and rain, the two libraries have continued to develop and uphold the common cultural memory of humanity, while maintaining their original buildings and collections. In 1561, Fan Qin, the right attendant of the Ming Dynasty's Ministry of War, began building the Tianyi Pavilion after returning to his hometown Ningbo after finishing his official career, in order to collect the books he had collected throughout his life and leave behind this earliest surviving private library in China. Jiangnan is humid and rainy, and it is not easy for Tianyi Pavilion to still maintain the appearance of a two-story wooden structure when it was built, "said Zhuang Lizhen, the director of the Tianyi Pavilion Museum. Today, the protection area of Tianyi Pavilion has expanded from over 2000 square meters at the beginning of the founding of New China to 30000 square meters, and its collection has increased from 70000 volumes to 300000 volumes. At the Tianyi Pavilion, Zhuang Lizhen showcased to reporters a Qing Dynasty copperplate painting "The Victory of the Pingding Hui tribe" that was collected by the Tianyi Pavilion. This set of copperplate paintings was created by Giuseppe Castiglione, an Italian and a court painter of the Qing Dynasty, and then sent to Europe for plate making. It is a masterpiece of combining Chinese and Western styles. In 1571, on the square in the center of Florence, the Medici Lorenzo Library built by the Medici family was officially opened. The museum is designed by Michelangelo and has a classical style reading room of over 400 square meters, with a collection of over 11000 manuscripts and 4500 early printed books. No matter how the world changes, no matter how human means of preserving culture change, books have always been one of the most cherished parts of human civilization. As the main carrier of physical book preservation, the library has a unique cultural and historical value of preserving the common memory of humanity. "In November 2022, Sylvia Hipioni, the director of the Medici Lorenzo Library, said during a library "Cloud Dialogue" event organized by Tianyi Pavilion. Hippioni said, "We will actively devote ourselves to the protection of the library, the research of the collection, and the dissemination of the collection culture. We will actively promote the construction and development of contemporary book culture, and it is our common mission and responsibility to protect the most unique cultural memory of humanity." Although separated by mountains and rivers, safeguarding the common cultural heritage of humanity is the same belief and mission of the two libraries. In recent years, in addition to protecting existing cultural heritage such as books, the Medici Lorenzo Library has also accelerated modernization by digitizing its collection of manuscripts and modern books, and offering remote cultural courses for readers. At the same time, Tianyi Pavilion is also adopting modern methods to scan its collection of ancient books, build a digital resource library of ancient books, and build a modern ancient book warehouse with constant temperature and humidity, creating a safer and more stable environment for the storage of cultural relics. Readers can also study and utilize ancient books without being exposed to physical objects. Nowadays, over 200000 people visit our resource library website every year, effectively solving the contradiction between the preservation and use of ancient books, "said Zhuang Lizhen. I hope that on this year's World Book Day, everyone can pay more attention to paper books and libraries, and join the team of loving books, reading, collecting books, protecting books, repairing books, and passing on books together, so that our book fragrance can spread further and make
