摘　　要：The hadronic molecular state picture is one of the most popular interpretations of the exotic state in market[1].It has been widely applied to explain a series of experimentally observed exotic states,which can not be assigned in conventional quark model but is close to the threshold of two hadrons.In the literature,people often focus on the bound state from S-wave interaction and assume P-wave bound state should be difficult to form from hadronhadron interaction and to observe in experiment.For example,the Y(4274)and the Y(4140)are related to the S-wave Ds￣D s0(2317)and Ds^*+Ds^*-states,respectively[2,3].
