The judge complained about the lack of marriage information nationally, saying she would like to see the loophole closed. Women ought to have a full understanding about a man before getting

 married to him, she said.

"Some women blindly marry because they think they're getting old and have a lot of pressure from family, which is not sensible," she said.

Liu, the Beijing lawyer, said people face two years in prison at most for bigamy under the current Chinese Criminal Law.

He suggested that public security bureaus responsible for managing residency should update marriage information in a man's household booklet.
