Beyond serving in the administration and the judiciary, scholar-officials also provided government-funded social services, such as prefectural or county schools, free-of-charge public hospitals, retirement homes and paupers' graveyards. Scholars such as Shen Kuo (1031–1095) and Su Song (1020–1101) dabbled in every known field of science, mathematics, music and statecraft, while others like Ouyang Xiu (1007–1072) or Zeng Gong (1019–1083) pioneered ideas in early epigraphy, archeology and philology.
