Liuding Mountain

There are ancient tombs on the mountain, which was the graveyard of the royal family of the Balhae kingdom. The tombs were excavated by Yanbian University, Jilin Provincial Museum, and the Archaeology Research Institute of the Chinese Academy of Sciences in 1949, 1959 and 1964. There are more than 90 different tombs, including the tomb of Princess Zhenhui, one of the children of Mun of Balhae. The tomb was built of basalt and fulgurite. Many objects were found: pottery, gold-plated copper jewellery and jade. Her tombstone (90 x 49 x 29 cm) bears an epigraph of more than 700 characters written in Chinese, which is an indication that the Balhae kingdom used Chinese characters, making the stone historically significant.^[2]

Some people claim that Liudingshan is the true location of Dongmu Mountain, the first capital city of the Balhae kingdom.^[3]
