The PandaX (Particle and Astrophysical Xenon) experiment, located in the world deepest underground laboratory, China Jinping Underground Laboratory (CJPL), is dedicated to search for dark matter particles and to study fundamental properties of neutrinos. The current stage experiment, PandaX-4T, contains a sensitive time-projection-chamber with 3.7-ton liquid xenon target. The commissioning run of PandaX-4T has been completed in 2021. In this talk, after an overview of this project, I will present our first dark matter search with the commissioning data, and discuss future prospects of PandaX.
