Based on observations from the Transiting Exoplanet Survey Satellite (TESS), we conducted a comprehensive study of two contact binaries, V752 Cen and HT Vir, in 2+2-type hierarchical quadruple stellar systems. TESS continuous light curves (LCs) reveal that exhibits random-walk-like or quasi-periodic...
