In this paper, a model-independant amplitude for the decay process of psi'-->J/psi pi (+) pi (-) is constructed from a few basic rules:Lorentz invariance, PCAC (Partial Conservation of Axial Current) and QCD low energy theorem. Based on this amplitude, a new and complete partial wave analysis to this process is carried out. Formulae of angular correlation distribution, invarant mass spectrum and two dimension (joint angular correlation and invarant mass) distribution are given. It is pointed out that there exist D - wave in the psi'-->J/psi pi (+) pi (-) process and part of the D - wave is caused by recoil of J/psi.
