The etiquette that was inseparable from law should have been transmitted with Chinese legal codes, but the expression wasn't always limited to the legal codes text. Especially in the case of the ideas of ritual, It was considered that fixed change occurred due to the difference in the consept of ghost and god between the two countries. And after examinating of records about rei, it was found that there were rei of the spirit who brought an epidemic and rei of the ghost who had no heir in the ancient China. New development of beliefs to rei in the late of Han Dynasty and the Six Dynasty was a result that these two kinds of rei were connected under the condition of the deaths in hatred. That's the customs which worship the vindictive spirit who was a concrete person to a god. These customs can be considered to have an impact on Japan. In addition, This work also looked at the first Goryō ceremony and subsequent Goryō ceremony and pointed out that the origins of both were different, and speculated that the former possibly imitated Chinese ritual of rei for political purposes.
