The Symbiotic star (SySt) is a long-period interacting binary system, typically consisting of a white dwarf (WD) and a red giant surrounded by a nebula. These systems are natural astrophysical laboratories for investigating binary star evolution. In this paper, we identified nine SySts from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR10 low-resolution spectra survey, seven of which were previously known, while two are newly identified. Initially, we selected LAMOST spectra exhibiting typical SySt emission lines (e.g., H_α, H_β, H_γ, and He II). Subsequently, we utilized the distribution of known SySts on the Hertzsprung-Russell diagram to select SySt candidates, and visually inspected their spectra. Ultimately, we classified all nine as S-type SySts using the J - H versus H - K_s diagram. Additionally, based on multiband photometric data from GALEX, Gaia, Two Micron All Sky Survey, ALLWISE, and several X-ray catalogs, we found 12 accreting-only SySt (acc-SySt) candidates, characterized by concurrent ultraviolet and infrared excess and accretion process. Furthermore, we estimated the WD temperatures by fitting their observed spectral energy distributions using a combination of the Kurucz stellar atmosphere model and the Koester WD model. We compared the accretion rates of acc-SySt candidates and confirmed SySts, and found they have similar accretion rate distributions, providing evidence that these acc-SySt candidates constitute bona fide SySts.
