Neutrinos were thought to be massless for decades. However, a series of experiments has recently provided compelling evidences for neutrino oscillation, a new phenomenon that implies the three types of neutrinos observed in laboratories do have mass after all. Neutrino oscillation can be described with a set of three neutrino-mixing angles, of which the smallest one called q13 was unknown. Using low-energy electron antineutrinos generated by a group of running nuclear reactors, the Daya Bay experiment discovered a new kind of neutrino oscillation due to a non-zero value of q13 in 2012.  Since then, the experiment has acquired a lot more data. In this talk, the latest results and prospects of Daya Bay will be presented. The implications of this surprising observation will also be highlighted.
