In the present work, we investigate the productions of and its spin partners in the decay processes, where is regarded as a 
molecular state. We infer that the initial meson and the final 
are connected through the 
mesons by exchanging a 
meson. The contributions of such a meson loop to the process 
are evaluated and our estimations indicate that the measured branching fraction of 
could be well reproduced in a reasonable range of model parameters, indicating that could be interpreted as a molecular state. In addition, the production processes 
, 
, and 
are investigated, and we find that the fit fraction of 
in the process 
is about 6%, which should be accessible by the LHCb and Belle II Collaborations.
