By using the CCD detector and Cassegrain spectrograph of the 2.16 m telescope at Beijing Astronomical Observatory, we are carrying out optical identifications of the X-ray sources selected from the ROSAT All-Sky Survey Bright Source Catalogue. We present here the discovery of 9 bright low-redshift quasars.
