Abstract: In phenomenology of quantum chromodynamics (QCD), charmed meson vertices are useful tools to study the final-state re-scattering effects in the hadronic B decays. The strong couplings of charm mesons vertices, are related to the basic parameters in the heavy quark effective Lagrangian. Here, the four-flavor Hard-Wall holographic QCD is illustrated to evaluate the couplings of $$(D^{_{-(*-)}}, {\bar{D}}^{_0}, a_{1}^{_-})$$ ( D - ( ∗ - ) , D ¯ 0 , a 1 - ) , $$(D^{_{-(*-)}}, {\bar{D}}^{_0}, b_{1}^{_-})$$ ( D - ( ∗ - ) , D ¯ 0 , b 1 - ) , $$(D_{s}^{_{-(*-)}},{\bar{D}}^{_{0}}, K_{1A}^{_-})$$ ( D s - ( ∗ - ) , D ¯ 0 , K 1 A - ) , $$(D_{s}^{_{-(*-)}}, {\bar{D}}^{_{0}}, K_{1B}^{_{-(*-)}})$$ ( D s - ( ∗ - ) , D ¯ 0 , K 1 B - ( ∗ - ) ) , $$(D_{s}^{_{+(*+)}}, {D}^{_+}, K_{1A}^{_0})$$ ( D s + ( ∗ + ) , D
