At designed CEPC, similar to hadron collider, the angular distributioncoefficients of decay lepton pair from produced Z(W) boson in $e^+ e^-$collisions are predicted. Their dependence on $cos\theta_Z$($cos\theta_W$) arepresented in four different polarization frame. Furthermore, the value ofangular coefficients in different bins of $cos\theta_Z$ are presented in theC-S frame. In comparison to the case at hadron collider, better accuratemeasurement for $Z(W)$ is expected since there exists less background and $W$could be reconstructed from it's leptonic decay channel. This work supply a wayto precise test the electroweak production mechanism or some effect inducedfrom new physics in the future measurements at the CEPC.
