We study the

decays, which have been recently measured by the BESIII collaboration. We propose that 
receives the contributions from the triangle rescattering processes, where 
and 
in 
, by exchanging 
, are formed as 
and 
, respectively, with 
. Accordingly, we calculate that 
and 
, being consistent with the data.
