During the late 1950s and early 1960s, the regional government organized cultural relics investigation groups to systematically investigate relics and remains including ancient structures, tombs, stealer and cliff face inscriptions and petroglyphs. Soon after, specialized cultural relics administration organs were set up. The tens of thousands of the cultural relics collected were individually registered and gathered together in protective custody. Items gathered included the uniquely rare sutra written on pattra palm leaves, the pearl tangka now kept in the Qamzhub Monastery and an imperial decree installing local officials, seals of authority, gold-leaf certificates of appointment, inscribed tablets, and a wide variety of precious stones and utensils all emanating from the Central Government from the Yuan Dynasty on. Also found were Yuan Dynasty paper money, memorials, documents and letters addressed by the local government of Tibet and regional leaders to the Central Government and many bronze and stone inscriptions, seals, murals and memorial tablets. In an effort to preserve precious cultural relics, the Chinese Government in 1961, 1982 and 1988 declared a total of 13 sites as State-level key cultural relics preservation units. The regional government has declared 11 sites as regional-level key cultural relics preservation units.

At present, all major cultural relics preservation units already renovated and put into order are open to tourists from home and abroad. Such units and the sites of religious activities are open year round to Buddhist pilgrims. The Cultural Relics Preservation Department has been invited to various countries and regions in Europe, Asia and America to hold cultural relics exhibitions of varying scale.
