Gao Xiaoying (L), a paediatrician specialized in infant health care, shows a young mother how to give health exercises to her baby at the Provincial Maternal and Child Hygiene Hospital in Wuhan, capital of central China's Hubei Province Sept. 6, 2004. China started its family planning policy from the early 1970s. The Law of the People's Republic of China on Population and Family Planning went into effect on September 1, 2002. The law stipulates that the country encourages a couple to bear one child, and they can have a second one if their circumstances meet the provisions. This family planning policy has been proved correct and it has a great positive effect on China's economic and social development.
