  　LAMOST (also named the Guoshoujing Telescope) is a quasi-meridian reflective Schmidt telescope with an effective aperture of 4m. It is equipped with 16 spectrographs fed by 4,000 optical fibers distributed in a field of view of 20 sq.deg. The spectra cover the whole optical wavelengths from 370 -- 910nm at a resolving power of 18,00. The LAMOST Galactic surveys were initiated in the fall of 2012. It is expected to collect over 7M stellar spectra over a five-year survey period. Hitherto, over 3M spectra have been collected. In this talk, I will present a short review of the scientific motivations, target selections, survey progress, data reduction and products, as well as the early scientific results of the surveys
