In this work, we study the $J/\psi\pi$ and $\bar{D}^*D$ invariant massspectra of the $Y(4260)$ decay to find out the origin of the $Z_c(3900)$ and$Z_c(3885)$ structures. The $J/\psi \pi-\bar{D}^{*}D$ interaction is studied ina coupled-channel quasipotential Bethe-Saltpeter equation approach, andembedded to the $Y(4260)$ decay process to reproduce both $J/\psi\pi^-$ and$D^{*-}D^0$ invariant mass spectra observed at BESIII simultaneously. It isfound out that a virtual state at energy about 3870 MeV is produced from theinteraction when both invariant mass spectra are comparable with theexperiment. The results support that both $Z_c(3900)$ and $Z_c(3885)$ have thesame origin, that is, a virtual state from $J/\psi \pi-\bar{D}^*{D}$interaction, in which the $\bar{D}^*{D}$ interaction is more important and thecoupling between $\bar{D}^*{D}$ and $J/\psi\pi$ channels plays a minor role.

$Z_c(3900)/Z_c(3885)$ as a virtual state from $\pi J/\psi-\bar{D}^*D$ interaction
