Before the founding of New China in 1949, Chinese women’s life expectancy was only 37.6 years. A girl born today can expect to live an average of 72 years. Hygienic practices barely existed for mother and children in the early 1950s, said a health worker who remembers that period. Maternal mortality was high as a result of traditional midwifery practices, which often caused childbed fever.展开更多

The Law of the P.R.C. on the Protection of Mothers and Infants, passed on October 27, 1994, during the 10th Session of the 8th Standing Committee of National People’s Congress, was publicly issued on the No.33 Command of the President of the P.R.C. and will go into effect June 1, 1995. This first law specifically concerned with the protection of the health of women and children is expected to play an important role in the overall improvement of the health of the Chinese people, the quality of the population, the advancement of the society, and the overall happiness among families.
