This paper mentions observations of eight totally eclipsing contact binary stars, 'light curve.xlsx' is the observation data of the eight targets. From 2019 to 2021, we used the 60 cm Ningbo Bureau of Education and Xinjiang Observatory Telescope (NEXT) in China to observe the eight contact binary stars. This telescope is equipped with an FLI PL23042 CCD and has a field of view of 22'× 22'. During the observations, standard Johnson–Cousins filter and Sloan filter were used. And 'Table9.xlsx' is the eclipsing times of them, including data from the O-C Gateway and AAVSO, as well as global photometric surveys ASAS-SN, ZTF, TESS, and SuperWASP.
