  The successful measurements of the smallest neutrino mixing angle,
$\theta_{13}$, in 2012 by the short (1$\sim$2 km) baseline reactor neutrinos
experiments, Daya Bay, RENO, and Double Chooz, have triggered a golden age of
neutrino physics. The three experiments have been improving the $\theta_{13}$
measurements by accumulating event statistics and reducing systematic
uncertainties. Now the $\theta_{13}$ measurement is the most precise one among
the mixing angles in the Pontecorvo-Maki-Nakagawa-Sakata matrix. The most
updated $\theta_{13}$ and $\Delta m^{2}_{ee}$ measurements from these
experiments are reported here as well as the 5 MeV excess, absolute reactor
neutrino flux and sterile neutrino search. The best final precision on the
sin$^{2}2\theta_{13}$ ($|\Delta m^2_{ee}|$) measurement is expected to be
$\sim$3\% ($\sim$3\%). A combined analysis from the three experiments will
reduce the uncertainty and the relevant activity has started recently.
