In this paper, we develop a series of event generators on the BESIII detector to study the decays of \$\eta/\eta^\prime\tol^+l^-\$, \$\eta/\eta^\prime\to\pi^+\pi^-\$, \$\eta^\prime\toømega e^+e^-\$, \$\eta\to\pi^+\pi^-\pi^0\$, \$\eta/\eta^\prime\to\pi^0\pi^0\pi^0\$, \$\eta^\prime\to\eta\pi\pi\$ and \$\eta'\to\pi^+\pi^-\pi^+\pi^-/\pi^+\pi^-\pi^0\pi^0\$. Monte Carlo simulation distributions show that all event generators are performing very well. The consistence between our simulation distributions and the BESIII results examine the usability of the \$\eta/\eta^\prime\$ generators which can be also used in other \$\eta/\eta^\prime\$ factories and improved by further experiment results.
