In this work, we apply an important non-perturbative QCD effect, i.e., hadronic loop mechanism, to study $\\chi_{c1}\\to \\gamma V$ radiative decay. Our numerical result shows that the theoretical results including the hadronic loop contribution and the PQCD calculation of $\\chi_{c1}\\to \\gamma V$ are consistent with the corresponding CLEO data of $\\chi_{c1}\\to \\gamma V$.
