In northwest China in tombs near Mogou village, archaeologists have found hundreds of graves that contain the remains of victims of human sacrifice. This cemetery dates back more than 4,000 years.
The excavation of the tombs took place between 2009 to 2011. The 
majority of them are believed to belong to the Qijia culture. Not only 
were there individual burials, but in some cases entire families were 
interred with their heads facing northwest.
Adjacent
 to the remains were small rooms containing pottery, as well as 
necklaces, bronze sabers, maces, axes daggers and knives.
