Description
The BESIII experiment has collected 2.6 billion $\psi(3686)$ events, 10 billion $J/\psi$ events, 20 $fb^{-1}$ of D meson pairs at 3.773 GeV, and 7.33 $fb^{-1}$ of $D_sD_s^*$ events from 4.128 to 4.226 GeV. The huge data samples allow us to search for rare processes in charm hadron decays. In this talk, we report searches for FCNC decay $J/\psi \to D^0\mu^+\mu^-$ and $D_s^+ \to h(h')e^+e^-$. The searches for $J/\psi$ weak decays containing a D meson and for $J/\psi \to \gamma D^0$ will also be presented.
