We study the possible heavy molecular states composed of a pair of charm mesons in the H and S doublets. Since the P-wave charm-strange mesons $D_{ s0}(2317)$ and $D_{ s1}(2460)$ are extremely narrow, the future experimental observation of the possible heavy molecular states composed of $D_s/D_s^\ast$ and $D_{ s0}(2317)/D_{ s1}(2460)$ may be feasible if they really exist. Especially the possible $J^{ PC}=1^{ --}$ states may be searched for via the initial state radiation technique.
