Query: A Monte Carlo Generator for Full Simulation of e+e- to hadrons Cross
  section Scan Experiment   A generator with $\alpha^2$ order radiative correction effects, including
both the initial state radiative corrections and the photon vacuum polarization
corrections, is built for the full simulation of $e^+e^- \to hadrons $ in cross
section scan experiment in the quarkonium energy region. The contributions from
the hadron production structures including the resonances of $1^{--}$
quarkonium families and the light hadrons spectrum below 2 GeV as well as the
QED continuum hadron spectrum are all taken into account in the event
generation. It was employed successfully to determine the detection efficiency
for selection of the events of $e^+e^-\to hadrons$ from the data taken in the
energy region from 3.650 GeV to 3.872 GeV covering both the $\psi(3686)$ and
$\psi(3770)$ resonances in BES experiment. The generator reproduces the
properties of hadronic event production and inclusive decays well.
