The LAMOST survey provides more than seven million spectra of stars which brings key information of basic parameters for those targets, building the largest stellar spectra library now and onward. Precise constraints on a great number of pulsating stars can be given by combining the LAMOST data with the photometric data from ground and space. In this talk, we first present the result of the discovery of four new DA pulsating white dwarf stars from the LAMOST survey. The followed-up observations from ground suggest that the detected pulsations in all these four stars are above the typical S/N~4. We then show the result of a Delta Scuti star, observed by Kepler and LAMOST together, which is possibly a long period binary system as revealed by the time pulsation technique. We finally propose some related projects aiming at mode behaviours (amplitude and frequency modulations) in the compact (white dwarf and hot subdwarf) stars observed by Kepler and LAMOST.
