Police also received a report from a motorcycle taxi driver who said he was carrying a suspicious passenger, with a girl who "wouldn't stop crying".
"I asked the woman if she was a human trafficker as the little girl she was with just kept crying," the man reportedly told police officers.
"Then I asked the girl if she knew the adult, she replied 'no'," he added.
Police found and arrested the woman two hours later, near the entrance of a highway.
The woman is reportedly deaf-mute and told police, through a sign language interpreter, that someone had paid her 10,000 yuan (about NZ$2000) to abduct children.
The little girl has been returned to her parents safely and police continue to investigate.
