Recent physics results at Beijing Electron-Positron Collider (BEPC) are reviewed, especially on excited baryons. Substantial improvements are expected at the newly built BESⅢ experiment, which is operational since 2008. The detector performance is excellent and a total of 100 million ψ(2S) and 200 million J/ψ event are collected in 2009. Preliminary results shows that a new era of excited baryon physics will begin.
