The word Delinha is from the Mongolian language and means golden grassland where the Sun rises. 

   The high elevation, dry atmosphere, and nice weather conditions make  Delinha an excellent place for millimeter-wave radio observation. 

   The primary facility of Qinghai observation station is the 13.7m radio  telescope equipped with an indigenously developed SIS superconductor  receiver working in the band of 85-115 GHz. The telescope is the only  radio facility working in millimeter waveband in China and is fully open  to the community. The observations of the spectral lines of CO  isotopes, HCO+, SiO, CS, etc and continuum spectra with the telescope  are widely used for the study of molecular cloud structure, physical and  chemical environment of star formation regions, planet nebula,  supernova remnant, molecular line survey, solar continuum radio spectrum  and nearby galaxies. 

   Nowadays, Qinghai station is upgrading the telescope by equipping it  with a multi-beam receiver. The telescope will have much more powerful  mapping ability when the reform is done.  

   With its newly equipped facilities, the station is now carrying on a  large science project --- the Milky Way Imaging Scroll Painting (MWISP)  project, which is the first no-bias high sensitive large scale CO survey  towards the Galactic plane. 

  Apart from the 13.7m radio telescope, Qinghai station is also equipped with some optical telescopes which belong to the National Astronomical Observatory of CAS and the China West Normal University used for the observations of celestial objects in solar system and other science targets.
