Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a meridian reflecting Schmidt telescope with an average clear aperture of 4-meter, a focal length of 20-meter and a field of view of 5-degree. It is a national large scientific project in China. The horizontal meridian reflecting Schmidt configuration and with an active Schmidt correcting plate to achieve the special telescope with both wide field of view and large aperture. There are 4000 optical fibers on the focal surface to transfer light of 4000 objects into 16 spectrographs. The project started in 1997. Now it steps into its assembly stage. The general status and progress of LAMOST project is presented in this paper: The key technologies of the project have been tested successfully; the design and manufacturing of the mechanical parts of the telescope have been completed; most segmented mirrors (sub-mirrors) have been polished. Also the first spectrograph, the first three sub-mirrors of Ma (Schmidt plate) with their complete support system, and the first three sub-mirror of the primary mirror are ready for being integrated on the telescope structure
