In this work, we present a set of M-type star candidates selected from the LAMOST DR3. A discrimination method with the spectral index diagram is used to separate M giants and M dwarfs. Then,we have successfully assembled a set of M giants templates from M0 to M6, using the spectra identified from the LAMOST spectral database. After combining the M dwarf templates in Zhong et al. (2015) and the new created M giant templates, we use the M-type spectral library to perform the template-fit method to classify and identify M-type stars in the LAMOST DR3.
