%X In this article, we derived the transformations among three sets of elosed time path Green's functions and some calculation rules, from which a general definition of arbitrary multipoint retarded and advanced Green's functions follows naturally. Some algebraic identities among multipoint functions have shown to be the consequences of the property WJ+,J-](J+=J-=J)=0 for the generating functional on the closed time path.
