The Fermilab E989 experiment has recently reported their result of muon
anomalous magnetic moment ($g$-2). Combined with the E821 result, the
discrepancy with the Standard Model (SM) reaches $4.2sigma$, which may
indicate the light new physics related with the electroweak interactions. On
the other hand, the observed Galactic Center GeV Excess (GCE) and anti-proton
excess can also be explained by the light weakly interacting massive particle
dark matter. In this work, we attempt to pin down a common origin of these
anomalies in the Next-to-Minimal Supersymmetric Model. By considering various
constraints, we find that the eletroweakinos and sleptons have to be lighter
than about 1 TeV, and the geometric mean of their masses need to be less than
about 375 GeV to interpret the muon $g-2$ within $2sigma$ range. In order to
accommodate both the muon $g-2$ and GCE, the bino-like neutralino DM is needed
and has to resonantly annihilate through the $Z$ boson or Higgs boson to give
the correct relic density. Besides, the DM annihilating cross section for GCE
can be achieved by a singlet-like Higgs boson via $s$-channel. If the
anti-proton excess is explained together, only the Higgs funnel is feasible. We
point out that the favored parameter space to explain all these anomalies can
be probed by the future direct detection experiments.
