  The BESIII experiment has collected world's largest direct $e^+e^-$ colliding
beam data at the $J/\psi$, $\psi'$, $\psi$(3770) and at and around the
$Y$(4260). These data have enabled the study of hadrons at unprecedented
precisions. We present results on the light hadron spectroscopy, production of
hadrons in radiative decays of charmonia, observation of new excited $N^*$
baryons and of anomalous decays of the $\eta/\eta'$ states.
