We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the china Dark Matter Experiment(cDEX), based on the data from both cDEX-1B and cDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(c.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from cDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% c.L. We for the first time extended the limit to the m_(χ)c^(2) region.
