Sex education
Sex education lags in China due to cultural conservatism. From ancient China to the first half of the 20th century, formal sex education was not taught. Instead, a woman's parents were mostly responsible for her sex education after she is wed. Many Chinese feel that sex education should be limited to biological science. Combined with migration of young unmarried women to the cities, lack of knowledge of contraception has resulted in increasing numbers of abortions by young women.
