To highlight the eternal value of publications in fostering mutual learning among civilizations and to call for increased attention from the publishing and international communication sectors, this research investigates the eternal value of publications in facilitating inter-civilizational communication and mutual learning, advocating for enhanced focus from the publishing and international communication sectors. Inter-civilizational communication and mutual learning serve as a bridge for international friendship, an impetus for human progress, and a bond for global peace. While avenues such as population migration, ethnic integration, cultural exchanges, trade, and religious dissemination have contributed, publications remain the essential medium across time periods, cultures, and regions—serving an irreplaceable role historically, presently, and in the future. Publications exert profound, extensive, durable, and distinctive influence in intercultural communication. They embody numerous distinctive values; from civilizational inheritance alone, their eternal values include: recording the chronicles of human civilization, preserving its collective memory, maintaining accumulated achievements. Beyond the Silk Road, Chinese civilization expanded through two Fragrant Books Paths: the westward path to the Western Regions, South Asia, Mediterranean, and Europe; and the eastward path through Japan to Asia-Pacific. Both paths advanced the global dissemination of Chinese culture. These exchanges are inherentlyreciprocal, as foreign civilizations integrated into Chinese civilization through publications, thereby enriching it via mutual learning. Publishing history reveals three significant climaxes of inter-civilizational communication. The First Climax is Xuanzang's Scripture Quest. Under Tang Dynasty support, Monk Xuanzang traveled west to acquire Buddhist scriptures. His subsequent 20-year translation project produced 1,335 volumes of Buddhist texts, catalyzing the sinicization of Buddhism. The subsequent publication of “Journey to the West” immortalized this exchange in Chinese cultural consciousness. The Second Climax is the introduction of Western learning into China. Publications introducing the Age of Enlightenment works on education, science, and philosophy entered China during the Westernization Movement (1861-1895). Western-style education and literature spurred new civilizational paradigms that transformed China. The Third Climax is the Marxist publications and their sinicization. The modernization of Japan after the Meiji Restoration served as a catalyst for Chinese students to study the Marxist literature. This initiated the pursuit of socialism with Chinese characteristics, facilitated through translated publications. These three climaxes demonstrate publications’ unmatched role in inter-civilizational communication —significantly exceeding transient interactions like visits or lectures. As noted by western philosophers, books are humanity’s greatest companions, enabling dialogues across time and borders with great minds. Publications are: faithful chroniclers of civilization, treasure houses of collective memory, compendiums of human achievement, carriers of intercultural exchange, envoys of mutual learning. Since China’s reform and opening-up, annual import/export of tens of thousands of copyrighted titles has sustained contemporary inter-civilizational communication. Every Chinese publisher is called to embrace this sacred duty: to disseminate China’s new civilizational paradigms through fact-based, rigorously crafted publications, while openly incorporating global innovations—thereby establishing lasting legacy for this generation in the annals of human progress.
