There is compelling evidence that about one-quarter of the energy density of the Universe is made up of dark matter, the nature and properties of which are unknown. Experimental studies of dark matter include production at accelerator, indirect detection of their decay or annihilation products, as well as direct detection of their interactions with normal matter. We will present an overview of the Dark Matter Problem, and on the direct detection front,  showing the diversity of experimental techniques and the variety of Beyond-Standard-Model physics being probed. We will take the CDEX light dark matter program with low-threshold germanium detectors at the China Jinping Underground Laboratory (CJPL) as illustrations.
