11 Vietnamese women were also rescued during the operation, as per Xinhua.
Investigations were launched after police came across a woman at a railway station, who bought a ticket with somebody else's identity in February last year. The man accompanying her tried to stop the police from talking to her, raising suspicions.
Upon probing, the authorities found out that the man, identified as Ren only, hailed from Anhui Province, and the woman was Vietnamese. He allegedly bought her from two men in Yunnan, according to the authorities.
