Searching for the neutrinoless double beta ($0\\nu\\beta\\beta$) decay is a promising way to probe the Majorana nature of neutrinos and provide insight into beyond Standard Model physics which might solve the matter-antimatter asymmetry in our current Universe. The China Dark matter EXperiment (CDEX) collaboration is planning and constructing a next-generation $0\\nu\\beta\\beta$ experiment (CDEX-300$\\nu$) to search for the 0𝜈𝛽𝛽 decay of $^{76}$Ge in China Jinping Underground Laboratory (CJPL). CDEX-300$\\nu$ will use about 225 kg $^{76}$Ge enriched germanium detectors coupled with passive and active background suppression technologies to conduct a "background free" search for the $^{76}$Ge 0$\\nu\\beta\\beta$ decay signal. The target $^{76}$Ge $0\\nu\\beta\\beta$ decay half-life sensitivity of CDEX-300$\\nu$ is 10$^{27}$ yr with one ton-yr exposure at a background level of 10$^{-4}$ counts/(kg·keV·yr) in the signal region, corresponding to a effective neutrino mass of 28.5-68.0 meV ranging by the uncertainty of the nuclear matrix element. In this paper, we present $0\\nu\\beta\\beta$ search efforts from CDEX and the preconceptual design of the CDEX-300$\\nu$ experiment.
