China is a big country with more than 1.3 Billion people.
The rate in which the population used to be growing according to chairman Mao’s policy that every family should have as many children as possible for the chinese revolution turned out to be quiet problematic.
To counter the uncontrollable increase of the population Deng Xiaoping and the Chinese Kommunist Party established the One-Child Policy in 1979 which is still effective and seems to control the population growth quite well.
But to live with this policy is not always easy for the people. China is a country with very family oriented people where the family has a strong social responsibility. If someone has no job or is retired he is supported by his family because the social system in China can only be described as basic up to the time of this writing.
When two people get married in China, traditionally it is said that one family looses a daughter and the other family wins one because the wife belongs to the family of her husband now. This is one reason why most chinese families love to have sons. The establishment of the One-Child-Policy amplified abortions in families who got the news that they will get a girl.
This was such a bad practice that nowadays doctors are not allowed any more to tell the becoming parents the sex of their offspring in advance.
