Abstract：
We question the validity of the multiplicity data 〈D ^*++D ^*－〉=0.43±0.07 in e ⁺e ^－annihilation at s= 29-35 GeV which is listed in Review of Particle Physics. After annalyzing five sets of data provided by five different collaborations, we derive the world average value: 〈D ^*++D ^*－〉=0.24±0.02 This result is in contradiction with that listed in Review of Particle Physics.
