Abstract: We report the progress of our search for new pulsating white dwarfs. A few pulsating DA white dwarf candidates were selected from the published catalogs based on the data of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. We carried out follow-up photometric observations on the candidates to ascertain if they are pulsators. Two candidates: J004628.31+343319.90 and J062159.50+252335.90 have been identified as new pulsating DA white dwarfs (ZZ Ceti stars). J004628.31+343319.90 has a main frequency at 2114.4μHz and J062159.50+252335.90 has a lower main frequency at 1204.6μHz.
