Based on a contact lagrangian that incorporates the SU(3) flavor and SU(2) spin symmetries, we discuss the symmetry properties of the interactions among the heavy flavor meson-baryon PψN, PψsΛ (with quark components [nc][nnc], [sc][nnc], or [nc][nsc]) systems and di-baryon H_ΩcccN, HΛ_Ωcccs (with quark components [nnc][ncc], [nnc][scc] or [nsc][ncc]) systems (n=u, d). The light quark components of the PψN (PψsΛ) and H_ΩcccN (H_ΩcccsΛ) systems have identical flavors, the interactions generated from the exchanges of light mesons in the PψN (PΛψs) systems should be very similar to that of the H_ΩcccN (HΛ_Ωcccs) systems. We perform the single-channel and multi-channel calculations on the PψN/PΛψs/H_ΩcccN/HΛ_Ωcccs systems and introduce the SU(3) breaking effect to identify the different mass spectra among the PψN (H_ΩcccN) and PΛψs (HΛ_Ωcccs) systems. We suggest two kinds of evidences for the existence of the flavor-spin symmetry among the heavy flavor PψN/H_ΩcccN/PΛψs/HΛ_Ωcccs molecule community, i.e., the mass arrangements of the PψN/H_ΩcccN/PΛψs/HΛ_Ωcccs mass spectra and the binding energies of the heavy flavor meson-baryon (di-baryon) systems attributed to the same contact potentials.
