After the Higgs discovery, precise measurements become vital for the experimental particle physics. A powerful Higgs factory, the Circular electron- positron Collider (CEPC), is proposed. The particle flow oriented reconstruction and detector design have been chosen as the baseline for the CEPC CDR studies. The performance of the physics benchmarks involving the reconstruction of jets at CEPC, including the individual jet responses and multi-jet identification, will be presented in the talk.
