In the framework of the chiral quark model (ChQM), we systematically investigate the strange hidden-charm tetraquark systems 
with two structures: 
and 
. The bound-state calculation shows that there is no any bound state in present work, which excludes the molecular state explanation (
) of the reported 
or 
. However, the effective potentials for the 
systems show the possibility of some resonance states. By applying a stabilization calculation and coupling all channels of both two structures, two new resonance states are obtained, which are the 
state with the energy around 4111–4116 MeV and the 
state with energy around 4113–4119 MeV, respectively. Both of them are worthy of search in future experiments. Our results show that the coupling calculation between the bound channels and open channels is indispensable to provide the necessary information for experiments to search for exotic hadron states.
