The higgsino world is one of the popular natural SUSY scenarios, in which . As such, searching for light degenerate higgsinos becomes an essential task of testing naturalness in supersymmetry (SUSY). In this work, we study the indirect effects of light higgsinos in the process at future Higgs factories, such as the Circular Electron Positron Collider (CEPC) in China. We find that the higgsino mass parameter favored by naturalness can be covered if the accuracy of the measurement of production can reach 0.1% at 240 GeV CEPC.
