Abstract: Reactor neutrino experiments have played irreplaceable roles in the history of neutrino physics and in recent years, two major ones have been built in Southern China, a short-baseline one, the Daya Bay Reactor Neutrino Experiment, and a medium-baseline one, Jiangmen Underground Neutrino Observatory (JUNO), which is currently under construction. Daya Bay discovered the value of θ 13 successfully and currently also holds the best atmospheric mass-squared difference measurement. The unexpected large value of θ 13 has also made the neutrino mass ordering measurement possible using reactor neutrinos, which is what JUNO is aiming to resolve by carefully arranging two oscillation frequencies onto the same energy spectrum. In this talk, we will give a general review on neutrino oscillation, the Daya Bay latest results, the design of JUNO and its current status.
