The collider ring provides e⁺ e⁻ collision at two interaction points (IP). The luminosity for the Higgs mode at the beam energy of 120GeV is 3*10³⁴ cm⁻²s⁻¹ at each IP while the synchrotron radiation (SR) power per beam is 30MW. Furthermore, CEPC is compatible with W and Z experiments, for which the beam ener-gies are 80 GeV and 45.5 GeV respectively. The lumi-nosity at the Z mode is higher than 1.7*10³⁵ cm⁻²s⁻¹ per IP. Top-up operation is available during the data taking of high energy physics. The status of CEPC will be introduced in detail in this paper.
