Results on steady TeV $\gamma$-ray point source search using data taken fromthe Tibet HD (Feb. 1997 -- Sep. 1999) and Tibet III (Nov. 1999 -- Oct. 2001)arrays are presented. From $0^{\circ}$ to $60^{\circ}$ in declination,significant excesses from the well-known steady source Crab Nebula and the highstate of the flare type source Markarian 421 are observed. Because the levelsof significance from other positions are not sufficiently high, 90% confidencelevel upper limits on the flux are set assuming different power law spectra. Toallow crosschecking, two independently developed analyses are used in thiswork.Comment: 21 pages, 6 figures. accepted by Ap
