Websites and apps whose users are mostly under age are the main target for the campaign, according to a statement of the CAC.
In a statement issued in April, the CAC said online pornography, violence, terror and superstition would be cleaned up.
After five days of collecting tip-offs and publicity, the CAC will investigate and crack down on the violators until the end of May.
Starting on June 1, it will also hold a week-long educational activity to raise the minors' awareness of cyberspace security.
According to the CAC, the Internet has become a main source of information and socializing for minors and the spreading of vulgar content will affect their mental and physical health.
