This talk briefly illustrates the status of low energy supersymmetr (SUSY) confronted with the current LHC data. Discussions on the current LHC data and comments on the status of particle theory are given. An introduction to low energy SUSY and a description for various SUSY models are presented. Finally, as an example, a global fit is performed for the popular constrained minimal supersymmetric standard model (CMSSM), considering the latest results of the LHC Run-2, the LUX experiments, the electroweak precision observables, the B-physics measurements and the Planck dark matter relic density. Then from the parameter space which is allowed or favored by the experiments, we see that the current fine-tuning extent of CMSSM is about 1/1000. Some attempts to improve the minimal SUSY models in light of the experimental data are also delineated.Point
