  The $WW$ production is the primary channel to directly probe the triple gauge
couplings. We analyze the $e^+ e^- \rightarrow W^+ W^-$ process at the proposed
Circular Electron-Positron Collider (CEPC), and find that the anomalous triple
gauge couplings and relevant dimension six operators can be probed up to the
order of $10^{-4}$. We also estimate constraints at the 14 TeV LHC, with both
300 fb$^{-1}$ and 3000 fb$^{-1}$ integrated luminosity from the leading lepton
$p_T$ and azimuthal angle difference $\Delta \phi_{ll}$ in the di-lepton
channel. The constrain is somewhat weaker, up to the order of $10^{-3}$. The
limits on the triple gauge couplings are complementary to those on the
electroweak precision observables and Higgs couplings.
