Here we present the latest results of the charged Lepton Flavor Violation process searches at the BESIII experiment in the decay of J/ψ to eμ, using (225.3±2.8)×106 J/ψ events collected with the BESIII detector at the BEPCII collider. An upper limit on the branching fraction of B(J/ψ→ eμ)<1.6×10-7 (90% C.L.) is obtained. The prospects and challenges with the future data are also discussed based on MC simulation.
