We perform a systematic study of the bound state problem of $D D ˉ$ and $B B ˉ$ systems by using effective interaction in our chiral quark model. Our results show that both the interactions of $D D ˉ$ and $B B ˉ$ states are attractive, which consequently result in $I^{G} (J^{P C}) = 0^{+} (0^{++})$ $D D ˉ$ and $B B ˉ$ bound states.
