Between the two A shaped tombs and the round rammed earth platform, five horse pits and a rectangular chariot pit were found. Six horses are buried in each of the two horse pits. The skeleton in one pit is neatly arranged in two rows of north and south, with 2 in the front row and 4 in the back, arranged in sequence from west to east; in the other pit, the skeleton of horses is arranged in a special way, with 6 horses in pairs or opposite sides, with different head directions. A special phenomenon is that a horn is placed in the middle of the horse pit
it is speculated that the horse pit may be related to sacrifice.
At the time of sacrifice, the horses sacrificed must be made in a consistent head-to-head shape.
