One of the most cited scholar that mentions female health is 7th-century scholar Sun Simiao. He is often quoted to the likes of "those who have prescriptions for women's distinctiveness take their differences of pregnancy, childbirth and bursting injuries as their basis." Even in contemporary "fu ke" does Sun's observations about female reproductive functions, it stills remains an important function of women's health. The propensity to place more emphasis on reproductive functions, rather than the entire health of the woman, seems to suggest that the main function of "fu ke" is to produce children.
