The tomb, facing toward south,is consisted of tomb passage,arched passage,light well,little niches and the passage to tomb chamber.Its total present length is 8 .2m.There are 120 items of relics,mainly of pottery figurines of human and animals discovered on their original places.The figurines are: heavenly Kings(天王) and guarding monsters at the two sides of the entrance to tomb chamber,11 animals of zodiac system along the four walls of tomb chamber,4 saddle horses in different postures and 2 comparatively large grooms.The figurines like standing human,horseriders and half statutes were placed inside the tomb chamber,other smaller ones like horse,ox,sheep,dog and pig were in the niches along the walls of the arched passage .Porcelain spitton,Tower-shaped Jar and lead vessels were found in the tomb chamber as well. There are well-preserved murals on the walls of tomb chamber and the passage to tomb chamber.In the tomb chambers on the east wall there is a dancing scene and flowers;the north wall,a snake and a turtle;The murals on west and south walls are not clear,but we still can see screens with flowers and grass design,and scarlet bird. The bomb should belong to the period of the Properous Tang.展开更多
