Starting in 2011, the Daya Bay Reactor Neutrino Experiment has been observing antineutrinos from six nuclear reactors with eight identically designed underground antineutrino detectors in three experimental halls. It has accumulated the world's largest dataset of electron antineutrino candidates. The measurement of the neutrino mixing angle $\theta_{13}$ and the neutrino mass squared difference $|\Delta m_{ee}^2|$ have reached a precision of better than 4%. The large dataset allows study of a variety of topics in neutrino physics, such as absolute reactor flux and spectrum. In this poster, we present the latest results from Daya Bay on several topics.
