Times Cited Count：32 Percentile：93.17(Astronomy & Astrophysics)-wave resonances in the fully charmed tetraquark system are studied in the quark model. The complex scaling method allows us to get the complex eigen-energies of the tetraquark system above the fall-apart decay thresholds. We found two resonances in each of the 
, 
and 
sectors, respectively. The obtained resonances are about 100 MeV higher than the recently found resonance,

, is studied in a constituent quark model. Four-body problem is solved in a variational method where the real scaling technique is used to identify resonant states above the fall-apart decay thresholds. In addition to the two bound states that were reported in the previous study we have found several narrow resonant states above the 
and 
thresholds. Their structures are studied and are interpreted by the quark dynamics. A narrow resonance with spin-parity 
is found to be a mixed state of a compact tetraquark and a scattering state. This is driven by a strong color Coulombic attraction between the 
quarks. Negative-parity excited resonances with 
, 
and 
form a triplet under the heavy-quark spin symmetry. It turns out that they share a similar structure to the 
-mode of a singly heavy baryon as a result of the strongly attractive correlation for the doubly heavy diquark.
