Police in Handan, Hebei province, are investigating the disappearance of more than 100 Vietnamese women who married local bachelors, and had been living in local villages. They vanished at the end of November.

Yuan Xinqiang, 22, from Quzhou county, married a Vietnamese woman in September after being introduced to her by Wu Meiyu, a Vietnam bride who has been living in another village in the county for about 20 years.

Since the beginning of this year, Wu had been saying she could introduce young Vietnamese women to local bachelors. If they liked each other, the man would pay Wu an amount of money based on his and the woman's ages, and then they could marry.
