  In these proceedings, we present the measurements of centrality, transverse
momentum and rapidity dependences of proton ($p$) and light nuclei ($d$
($\overline{d}$), $t$, $^{3}\mathrm{He}$ ($\overline{^{3}\mathrm{He}}$), and
$^{4}\mathrm{He}$) production in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ =
3 GeV, and isobaric (Ru+Ru and Zr+Zr) collisions at $\sqrt{s_{\mathrm{NN}}}$ =
200 GeV. The compound yield ratios in central collisions at 3 GeV are found to
be larger than the transport model calculations. Furthermore, the kinetic
freeze-out parameters at 3 GeV show a different trend compared to those of
light hadrons ($\pi$, $K$, $p$) at higher energies.
