The Daya Bay reactor neutrino experiment aimed to precisely measure the least known mixing angle θ13. In March 2012, Daya Bay announced the non-zero value with more than 5σ. With more statistics, less background and better control of systematics, the Daya Bay experiment is continuously improving the precision of sin2 2θ13 as well as the effective neutrino mass squared differences. In this paper, I will report the recent oscillation results, which are the most precise measurement of the oscillation parameter θ13 and . With 1230 days of data, sin2 2θ13 is measured to be [8.41 ± 0:27(stat.) ± 0.19(syst.)]×10-2, and = [2.50±0.06(stat.)±0.06(syst.)]×10-3eV2 with X2/NDF = 232.6/263. An independent measurement with the inverse beta decay neutron captured on hydrogen will also be presented.
