  Water masers are good tracers of high-mass star-forming regions. Water maser
VLBI observations provide a good probe to study high-mass star formation and
the galactic structure. We plan to make a blind survey toward the northern
Galactic plane in future years using 25m radio telescope of Xinjiang
Astronomical Observatory. We will select some water maser sources discovered in
the survey and make high resolution observations and study the gas kinematics
close to the high-mass protostar.
