There was a case of a China gal, very decent and knew nothing
about the law....but after got married 100% changed and go after
husband's $ and find lawyers to divorce husband....I think they
called her Xiao Long Nu...or something...
OMG!!!!!
my friend married a prc recently...... until now still ok......
unable to get PR, gahment ask her to go working so that can
contribute to the country, better chance to obtain PR, she seems
reluctant to go work leh........ but she do housework diligently at
home though...... 
Me now worried that if she get PR, then true colours all come
out then jia lak liao.....
