A ceremony of the official print publication of a series of selected archives in Tibetan, Mongolian, and Manchu was held in Southwest China's Tibet autonomous region on Tuesday.

According to the Tibet Archives Bureau, the region launched its collection and publication work since 2015 with the support of the National Archives Administration and the regional government.

The content of the series include ukases of kings from the Yuan Dynasty（1271—1368）, edicts of kings from the Qing Dynasty（1636—1912）, official letters, memorials, documents, inventories and notifications presented by institutions and officials of the Qing Dynasty, writs and letters of Tibetan local officials, Mongolian and Manchu aristocrats and nobles.

Yi Su, director of the archives management office of the region's archives bureau, said it took five years for more than 20 experts from across the country and staff of the bureau to complete the 12-volume project.

Su Faxiang, professor and head of the Tibetan Studies Institute at China's Minzu University, noted that as an important part of Tibet's cultural heritage, the work of exploration, collection, translation and publication of Tibetan archives has significant meaning for the promotion of Tibetan culture construction and academic research of Tibetan, Mongolian and Qing history.

"More than having a profound practical significance, the publication of the selected archives has high academic value."
