Recently, a new hidden-charm pentaquark state 
was reported by the LHCb Collaboration. Stimulated by the fact that all hidden-charm pentaquark states in 
systems were successfully studied by the chiral quark model, we extended this study to the systems. All possible states with quantum numbers 
, 
, 
, 
, 
and 
have been investigated. The calculation results shows that the newly observed state can be explained as 
molecular state and the quantum numbers are 
. In addition, we also find other molecular states 
, 
and 
. It is worth mentioning that can form a two-peak structure from states in system and . The decay width of all molecular states is given with the help of real scaling method. These hidden-charm pentaquark states is expected to be further verified in future experiments.
