Mangdang Mountain has a long history and belongs to the western extension of the hills in northern Anhui. It was formed in Mesozoic, about 0.8-10.37 billion years ago. During the Spring and Autumn Period, it belonged to Song State. At the beginning of Qin Dynasty, it was located in Dangxian and Dangjun counties, hence the name Dangshan. The ruins of Dangjun County still exist today. In the Western Han Dynasty, Mang County and Dang County were established. Dang County belonged to Liang State and Mang County belonged to Pei County. In the Eastern Han Dynasty, Mang County was renamed Linsui County. There are many cultural relics in this area, the most amazing of which is the Liangling Group in Damon, Western Han Dynasty. Its quantity, scale, high value and concentrated distribution are rare in the world and unique in China. A large number of cultural relics unearthed from Han tombs, such as jade clothes, bronzes, jade articles, gilded chariots and horses, are rare treasures with high archaeological research value. The "Four Gods Mural" in the Han Tomb is more than 600 years earlier than the Dunhuang Mural, and it is praised by the world as "Dunhuang before Dunhuang, and Dunhuang outside Dunhuang". The tombs of Liang Wang in the Western Han Dynasty are huge in scale and of extraordinary value, and were announced by the State Council as national key cultural relics protection units in 1996. In tourist areas, cultural relics of different times almost cover the whole process of China's historical evolution.

The most thrilling and archaeological attraction is the Royal Mausoleum of Liang Dynasty in the Western Han Dynasty. In the Western Han Dynasty, the kings and Mangdang Mountain belonged to the State of Liang, and the Liang Wang Liu Jian Liang Yuan was three hundred Li. He regarded Mangdang Mountain as a rare treasure trove of geomantic omen and spared no expense to build a mausoleum here. Since then, nine kings, queens and ministers of the State of Liang have been buried here after their deaths, forming a large-scale underground palace group. 1996, Liang Wang's Tomb Group of Western Han Dynasty in Mangdang Mountain was rated as "National Key Cultural Relics Protection Unit". So far, 22 royal tombs of the Western Han Dynasty have been discovered, and the tombs of the Empress and the King, which have been excavated and opened to the outside world, are shocking because of their complex structure and magnificent momentum.

Especially the Queen's Mausoleum in Liang Xiaowang, with a total area of 1.600 square meters and a volume of 6500 cubic meters. It consists of East Palace, West Palace and 34 storerooms. It's like a huge underground palace. Its age is 1300 years earlier than the Ming Tombs in Beijing, and its scale is twice that of Dingling. It is praised by Chinese and foreign archaeologists as "the first stone tomb in the world", and there are exquisite toilets, ice rooms and closets in the tomb. This is the masterpiece of the underground Han civilization and the crystallization of the wisdom of the ancient working people in China. There is also a 53-meter-long acacia tunnel in the Queen's mausoleum, which is said to be the underground passage for Liang Wang to meet the Queen.
