| contents | The Daya Bay reactor neutrino experiment, which pioneered the measurement of a non-zero value for the neutrino mixing angle $θ_{13}$ in 2012, operated for nearly nine years, from Nov.~24, 2011, to Dec.~12, 2020. Antineutrinos produced by six reactors, each with a thermal power of 2.9 GW, were detected by eight identically designed detectors located in two near and one far underground experimental halls. The experimental setup, featuring kilometer-scale baselines between the detectors and reactors, enabled precise investigations within the three-neutrino mixing framework. This proceeding presents the latest measurements of the neutrino mixing angle $θ_{13}$ and the mass-squared difference $Δm_{32}^2$, based on samples tagged via gadolinium capture ($n$Gd) and hydrogen capture ($n$H). The combined results from Daya Bay's most recent $n$Gd and $n$H data sets provide a $2.6\%$ precision for $\sin^22θ_{13}$. Additionally, a search for light sterile neutrinos with full data set is summarized. |
