Exemptions in China's 'one-child policy'

China says its restrictive family planning policy commonly known as the one-child policy, affects less than 40 per cent of its population.

But the government continues to promote the benefits of having just one child to all its citizens.

Some automatically fall under the exemptions but choose to have only one child anyway.
