Police rescued 98 victims and detained 464 suspects in a campaign that spanned 13 provincial regions, it said.
In November 2015, police in Changchun in northeastern province of Jilin were alerted to the criminal activity of a suspect identified only as Yang.
Yang was the ringleader of a gang that had abducted mute and hearing-impaired people and forced them to commit crimes with physical and verbal abuse.
The gang members allegedly posed as recruiters to gain the trust of the victims before abducting them.
