Liudingshan Ancient Tombs, Balhae-period tomb complex in Dunhua, China

Liudingshan Ancient Tombs is a Balhae-period (698–926) burial ground on Liudingshan, about 5 km south of Dunhua's urban centre in Jilin. It is divided into an eastern and a western cemetery, with more than 80 stone-chamber and earthen-mound tombs, mostly square or rectangular, built of basalt and lava and measuring roughly 2.5 to 3.5 m per side. Each chamber lies underground, entered through a passage in the south wall, with walls of irregular stone coated in white chalky earth.

The tombs belong to the royal family and nobility of the early Balhae kingdom (698–926), whose territory covered this part of Jilin. The best-known grave is that of Princess Jeonghye, second daughter of the third Balhae king Dae Heummu; excavated in 1949, it yielded a stele whose more than 700 incised regular-script characters record her death in 777 and burial in 780. The State Council designated the site a Major Historical and Cultural Site Protected at the National Level in 1961.

The tombs belong to the royal family and nobility of the early Balhae kingdom (698–926). The grave of Princess Jeonghye, second daughter of King Mun, was excavated in 1949; her stele, carved in regular script with over 700 characters, records that she died in 777 and was buried in 780. Grave goods included stone lions, agate beads, three-colour ware, and gilt-bronze and iron nails.

The tombs lie on Liuding Mountain, about 5 km south of Dunhua's urban centre in Jilin. The graves are split into an east and a west burial zone, so allow time to walk between the two areas. Tomb chambers are sunk underground and reached by a passage in the south wall.
