Description
Based on 10 billion $J/\psi$ events accumulated by the BESIII detector, we show
searches for the rare process of $J/\psi$ weak decays. We also search for other rare
decay process, such as the FCNC process $D^0\to\pi^0\nu\bar{\nu}$, and the $J/\psi\to 4
leptons$. Using $J/\psi$ decay, BESIII also produce millions of Hyperson, which can be
used to search for the rare decay process $\Xi^-\to\Xi^0e\nu_e$.
