A new method of searching for UHE point source has been developed. With a data sample of 150 million events, we have surveyed the sky for point sources over 3314 locations. It was found that their distribution is consistent with a random fluctuation. In addition, 52 known potential sources, including pulsars and binary X-ray sources, were studied. The source with the largest positive excess is the Crab Nebula. An excess of 2.5 sigma above the background is observed in a bin of 2.3 deg by 2.5 deg in declination and right ascension, respectively.
