The 1,700 years' old
Astana Ancient Graves (阿斯塔纳古墓群) are located in Erbao and Sanbao Villages, approximately 42 kilometers to the east of

A ten-meter-long sloping path in front of the tomb seen that leads to the chamber, where the deceased rests here forever.

Generally, the chambers in the graveyard are 2 meters height and about 4 square meters of area with flat or dome ceilings. Most dead bodies were placed in earth or on simple wooden bed that located in the back of the tomb chambers. Their heads are rested on pillows with their face covered with cloths, eyes closed and hands are grabbing the wooden edges of the beds. They are wearing cotton or silk woven garments. They are surrounded by architectural miniatures such as kiosks and pavilions, old carriages, ancient musical instruments and chesses, or food such as fruits, dumplings and cakes, for their comfortable in the afterworld life.
