China gives parents a break?

As we all know China was famous for its one-child-policy. If people don't know what it is then you need to re-read the title. It's when a family in China is only allowed to have one child, no more no less. They've been pretty strict about it for quite a while since they want to control the population in China. It worked so far and the population has been quite stable over the years. But in a recent article I have read China is going to allow families to have two children, but only if one parent is an only child. The main reason for the sudden change is that China is getting old, meaning there are more old people now a days than there are younger ones. In the future, if the one child policy was still in tact, there would probably have been too many old people and not enough young ones to take care of them. I think it's pretty weird that they only noticed now that China is an ageing country, but it's understandable that they are concerned for the old people.
