Recently, the BESIII Collaboration reported a new measurement of the ηcρ decay mode of Zc(′), which motivated us to study the inner structure of Zc(′) via investigating the hidden charm decays of these two Zc states. We consider the triangle loop mechanism contribution in the hidden charm decays of Zc(′). Our estimations indicate that the triangle loop mechanism plays an important role in the decays of the Zc(′), where our results are in agreement with the experimental observations in a reasonable parameter range. Furthermore, we point out that the Zc(′) can be interpreted as the hadronic molecules, while the tetraquark scenario is less favored.
