An elderly Chinese woman has won a court case against daughter for neglect, in terms of a controversial new law that requires grown children to look after their parents. 

Seventy-seven-year-old Chu Fudi sued her daughter and son-in-law, who she says don't visit her enough.

And the judge agreed.

Under a contentious new law, the judge ordered the pair to drop in on Chu at least once every two months - and on holidays.

The ruling is the first under a law that compels children to spend time with their elderly parents.

Critics though have called the measure government over-reach - and potentially counter-productive.

"If you settle this dispute through a lawsuit, the effect may be exactly the opposite of the intention," says this lawyer. "The relationship between the parents and their children may get even worse."

Chinese society traditionally places great importance on filial piety.

But three decades of dramatic social change and urban migration has left many elderly alone or in care homes.
