Bronze and pottery objects were found in the head boxes between the coffin and coffin chamber.
The Eastern chamber is located in the east of the main coffin chamber, which is in proportion to the western chamber.
Archaeologists designated the hall as the main coffin chamber, and the other three small interiors as the East chamber, the west chamber and the back chamber.
The west side room is located on the west side of the main coffin chamber, and is parallel to the main coffin chamber.
