We present a comprehensive investigation on the possibility of the search for new force mediator X boson in 
collision and 
decay at the BESIII experiment. The typical interactions of X boson coupling to leptons and quarks are explored. The production and decay properties of this X particle, the product/decay chains 
and 
, and exclusion limits on the reduced coupling strength parameters as functions of X boson mass are presented. With the data set of tens of 
or 
, we find that the exclusion limits on the coupling strength parameters fall in the range of 
, depending on 
assuming the decay width 10 eV
100 eV reasonably, for various hypotheses in the literature. According to our estimation, the search for new force mediator X boson in both collision and decay are accessible in nowadays BESIII experiment.
