Three neutral resonances , , and have been observed in the 
mass spectrum by the LHCb Collaboration. Given the 
and 
mass spectra predicted by the constituent quark models, these three resonances are tentatively treated as the 
-mode 
, 
, 
, and 
states, and their strong decay behaviors are calculated within the 
model. Our results indicate that the and can be clarified into the 
and 
states respectively, and the can be regarded as the 
state. Also, we suggest that the previous observed 
may be the overlap of two structures 
and 
, and the 
should be the same state as 
. Other theoretical information on the missing , , and states may be helpful for future experimental searches.
