We propose to measure the $HZ\gamma$ and $H\gamma\gamma$ anomalous couplingsin the process of $e^{+}e^{-}\rightarrow H\gamma$ with the sequential decay of$H\to b{\bar b}$. The discovery potential of observing the anomalous couplingsare explored in details. Our study shows that the electron-positron colliderhas a great potential of testing the $HZ\gamma$ and $H\gamma\gamma$ couplings.Conservative bounds on the two anomalous couplings are also derived when no newphysics signal were detected on top of the SM backgrounds.
