Inspired by the recent discovery of the doubly charmed tetraquark state 
by the LHCb Collaboration, we perform a systematic study of masses and strong decays of open charm hexaquark states 
. Taking into account heavy quark spin symmetry breaking, we predict several bound states of isospin 
, 
, and 
in the one boson exchange model. Moreover, we adopt the effective Lagrangian approach to estimate the decay widths of 
and their relevant ratios via the triangle diagram mechanism, which range from a few MeV to a few tens of MeV. We strongly recommend future experimental searches for the hexaquark states in the 
invariant mass distributions.
