We study the ratio of fragmentation fractions, , from the measurement of 
and 
with 
. With the branching fraction 
obtained under the U-spin symmetry, the fragmentation ratio is determined as
. To reduce the above uncertainties, we suggest to measure the branching fractions of 
and 
at BESIII, Belle II and LHCb.
