On May 16, 2025, a significant milestone in cultural diplomacy was marked as the Smithsonian’s National Museum of Asian Art in Washington, D.C. returned two volumes of the Zidanku Silk Manuscript—ancient Chinese texts dating to the Warring States period (475-221 B.C.)—to China’s National Cultural Heritage Administration. These volumes, titled “Decrees of the Five Elements” and “Offense, Defense, and Divination,” had been abroad for nearly 80 years and will be publicly displayed in Beijing’s National Museum of China in July 2025. The first volume, “Decrees of the Four Seasons,” remains in Washington[para. 1][para. 2][para. 3]. The Zidanku Silk Manuscript is renowned as the earliest known Chinese silk document and the only silk manuscript surviving from the Warring States period, offering unparalleled insights into ancient Chinese divination, cosmology, and philosophy, especially the concepts of Yin-Yang and the Five Elements[para. 2].

This repatriation owes much to Professor Li Ling of Peking University, whose four-decade scholarly pursuit culminated in the 2017 publication of a definitive study of the manuscripts. His research reconstructed both the artifact’s content and its global journey. The English edition, “The Chu Silk Manuscripts from Zidanku, Changsha (Hunan Province),” co-translated by eminent scholars, is being released in two volumes and represents an important achievement in cross-cultural academic collaboration. A launch event for this new edition is scheduled for June 22 in Beijing[para. 4][para. 5].

The Zidanku Silk Manuscript’s story began with its unearthing around 1943 near Changsha, Hunan—a region famous for dense ancient tombs plundered by local “earth masters” or “tu fuzi.” The four villagers who discovered it later became significant contributors to Chinese archaeology. The manuscript’s first collector, Cai Jixiang, acquired and published the first scholarly analysis of it in 1945[para. 6][para. 8]. However, the manuscript soon became embroiled in international intrigue: American John Hadley Cox, who developed ties to Chinese culture in the 1930s, arranged for the manuscript to be taken to the U.S. under the pretense of photographing it, later claiming he could sell it on Cai’s behalf, but failed to pay him and stopped communications after the Communist rise in China[para. 10][para. 11][para. 12][para. 13][para. 14][para. 15][para. 16][para. 17][para. 18][para. 19][para. 20][para. 21].

Over the following decades, the manuscript moved through various American museums, including the Nelson-Atkins Museum, Harvard’s Fogg Museum, and the Metropolitan Museum of Art, but was not sold for a long time. In 1966, collector Paul Singer recognized its value and facilitated its acquisition for Arthur M. Sackler. By 1992, Cox anonymously donated Volumes II and III to the Freer Gallery of Art and Sackler Gallery, while Volume I remained with the Sackler Foundation[para. 22][para. 23][para. 24][para. 25][para. 26].

Professor Li Ling’s work has been pivotal in reviving scholarly interest and advocating for the manuscript’s return to China. He was able to track its provenance through cooperation with American and Chinese academics. Despite various mishandlings, the manuscript’s rich text—ranging from calendrical lore to instructions on divination and military strategy—remains intact. Volume I details the schema of the four seasons, Volume II covers analysis based on Yin-Yang and Five Elements theory, and Volume III discusses strategic military divination[para. 28][para. 29][para. 30][para. 31][para. 32][para. 33][para. 34][para. 35][para. 36][para. 37][para. 38][para. 39].

Academics including Donald Harper and Lothar von Falkenhausen highlight the manuscript’s unparalleled linguistic, historical, and artistic value. Its painted deities constitute the earliest anthropomorphic representations in Chinese art. Ultimately, the Zidanku Silk Manuscript serves not just as a prized artifact but as a bridge for international scholarship and hopes remain for its complete reunification in China[para. 40][para. 41][para. 42][para. 43][para. 44][para. 45][para. 46][para. 47].
