In 1978 a law was introduced in China which stated couples could only have one child, as a result of the dramatic increase in population. Couples could apply to have a second child if the first was a girl or had an illness but few were approved. Parents across China decided they needed to get rid of their female/disabled babies. A loophole was soon found in the law. It was illegal to kill your child directly (as in to stab or shoot them)but it was not illegal to kill them through neglect. 'Orphanages' were opened to cater to the new demand. Parents would take their children there, where the staff would leave the children in rooms to die of thirst or starvation.
