Motivated by the searching for 
states at LHC recently, we calculate the ground-state energies of states with quantum numbers 
in a nonrelativistic chiral quark model using the Gaussian expansion method. In our calculations, two structures, meson-meson and diquark-antidiquark, and their coupling, along with all possible color, spin configurations are considered. No bound state is found, a resonance with mass of 19GeV is possible. It is expected that the studies shall be helpful for the experimental searching of fully heavy exotic tetraquark states.
