Using $(2712.4 \pm 14.3) \times 10^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, we search for the hadronic transition $h_{c} \to π^{+} π^{-} J / ψ$ via $ψ (3686) \to π^{0} h_{c}$ . No significant signal is observed. We set the most stringent upper limits to date on the branching fractions $B (ψ (3686) \to π^{0} h_{c}) \times B (h_{c} \to π^{+} π^{-} J / ψ)$ and $B (h_{c} \to π^{+} π^{-} J / ψ)$ at the 90% confidence level, which are determined to be $6.7 \times 10^{- 7}$ and $9.4 \times 10^{- 4}$ , respectively.
