Query: Two body hadronic $D$ decays   We analyze the decay modes of $D/D_s\to PP,PV$ on the basis of a hybrid
method with the generalized factorization approach for emission diagrams and
the pole dominance model for the annihilation type contributions. Our results
of PV final states are better than the previous method, while the results of PP
final states are comparable with previous diagrammatic approach.
