Daya Bay experiment and its future The Daya Bay reactor neutrino experiment completed its detector construction and installation in two stages. First physics results reported in March 2012，based on 55 days of data taking, claimed an observation of non-zerotheta-13, at a statistical significance of 5.2 sigma. New physics results based on 137 days data taking have been released recently, together with detailed analysis procedures. In summer 2012, all the eight neutrino detector modules were installed and commissioned. Data taking resumed in Oct. 2012 and will be continued for the next 3-5 years without interruption. A final uncertainty of about 4% to the oscillation amplitude is expected. A next generation reactor neutrino experiment for neutrino mass hierarchy measurement is now under planning in China. A short description of this experiment will be given.
