The bottom quark forward-backward asymmetry ($A_{FB}^b$) data at LEP exhibitsa long-standing discrepancy with the standard model prediction. We propose anovel method to probe the $Zb\bar{b}$ interactions through $gg\to Zh$production at the LHC, which is sensitive to the axial-vector component of the$Zb\bar{b}$ couplings. We demonstrate that the $Zh$ data collected at the 13TeV LHC can already resolve the apparent degeneracy of the anomalous$Zb\bar{b}$ couplings implied by the LEP precision electroweak measurements,with a strong dependence on the observed distribution of the $Z$ bosontransverse momentum. We also show the potential of the HL-LHC to either verifyor exclude the anomalous $Zb\bar{b}$ couplings observed at LEP throughmeasuring the $Zh$ production rate at the HL-LHC, and this conclusion is notsensitive to possible new physics contribution induced by top quark or Higgsboson anomalous couplings in the loop.
