Abstract
$J/\psi$ and $\psi'$ decays to mesons are a good place to look for glueballs, hybrids and for extracting strange and non-strange components in mesons. Abundant $J/\psi$ and $\psi'$ events have been collected at the Beijing Electron Positron Collider (BEPC). More data will be collected at upgraded BEPC and CLEO-C. Here we provide explicit PWA formulae for many interesting channels in the covariant tensor formalism.
