  Multiquark searches have been a hot topic in recent years. Some threshold
enhancements were observed during the analysis of 58M $\jpsi$ events collected
by BES II detector. These enhancements can't be explained by the standard model
and may be candidates of multiquark. BES also contribute a lot to the study of
light scalar mesons, such as $\sigma$,$\kappa$,$f_{0}(1370)$ and $f_{0}(1710)$
etc. Study of the excited baryon states and measurements of some $\jpsi$ decays
are also done with the $\jpsi$ events of BES.
