We construct three different sum rules from the two-point correlation function with pion, i fd4xeiq'x(O[TJN(X)JN(O)l~r(p)), beyond the soft-pion limit. The PS and PV coupling schemes in the construction of the phenomenological side are carefully considered in each sum rule. We discuss the dependence
