context: In 1939 Chinese Nationalist soldiers took the mausoleum from its position at the 'Lord's Enclosure' (Mongolian: Edsen Khoroo) in Mongolia to protect it from Japanese troops. It was taken through Communist-held territory in Yan'an some 900 km on carts to safety at a Buddhist monastery, the Dongshan Dafo Dian, where it remained for ten years. In 1949, as Communist troops advanced, the Nationalist soldiers moved it another 200 km farther west to the famous Tibetan monastery of Kumbum Monastery or Ta'er Shi near Xining, which soon fell under Communist control. In early 1954, Genghis Khan's bier and relics were returned to the Lord's Enclosure in Mongolia. By 1956 a new temple was erected there to house them. In 1968 during the Cultural Revolution, Red Guards destroyed almost everything of value. The "relics" were remade in the 1970s and a great marble statue of Genghis was completed in 1989.
