Is two-child policy changing China?

One year ago this week, China announced that what had become perhaps the most widely recognised symbol of Communist Party rule - the one-child policy - was to be scrapped.

It has been replaced instead with a new, universal two-child policy that took effect on 1 January this year.

To mark the first anniversary of the announcement, the BBC's John Sudworth set out to investigate what the new policy really means in practice.
