In the Circular Electron Positron Collider (CEPC), a measurement of the Higgs CP mixing through process is presented, with collision data at the center-of-mass energy of . In this study, the CP-violating parameter is constrained between the region of and 0.27 and between and 0.06 at confidence level. This study demonstrates the great potential of probing Higgs CP properties at the CEPC.
