After 11 years, a woman's Beijing household registration, or hukou, was nullified because authorities said she had used fake documents to obtain it.

The public security bureau of the capital's Dongcheng district canceled the Beijing hukou of Cheng Yuanyuan, saying she had used the university certificate of someone else, along with fake documents, to obtain her hukou in January 2005.

Liu Hongli, a teacher whose residence is in Xiangcheng, Henan province, said she found her hukou was void when she applied for a bank loan in September. She found that it had been moved to Beijing in the name of Cheng.
