Constructing the amplitude for the psi ..-->.. 3..pi.. decay from the five-point Veneziano function for KK-bar ..-->..3..pi.., we calculate the 3..pi.. Dalitz-plot density. This amplitude well explains the characteristic features of the experimental data. Calculation is also made with the Virasoro amplitude for the process psi ..-->..3..pi.. which was proposed by Cohen-Tannoudji et al. The Virasoro amplitude predicts an enhancement in the central region of the 3..pi.. Dalitz plot. This fact is in disagreement with the experimental plot. Ratios among relevant coupling constants and partial decay widths are evaluated with both our Veneziano amplitude and the Virasoro amplitude. Experimental data prefers our Veneziano amplitude for psi ..-->.. 3..pi...
