BESII is the updated version of BES, running in the Beijing Electron-Positron Collider (BEPC). In this talk, I will show the recent results got from the BESII J/Y and Y(2S) data samples, including the study of the \"rho-pi puzzle\" in charmonium decays, the hadronic and radiative transitions of charmonia, and the light hadron spectroscopy from J/Y, Y(2S) and c_cJ decays. The BESIII detector at BEPCII, designed as a tau-charm factory with peak luminosity of 10³³ cm^-2 s^-1 at Y(3770) peak, is being constructed, and is expected to start data taking in 2007. The status will be reported.
