The WeChat accounts, such as "zhebushilishi" (meaning this is not the history), spread fabricated information and confused the public, said the administration.
The censored accounts "were against laws and regulations", "disobeyed socialist core values" and "severely disturbed the online order"which should be punished in accordance with laws, state-run Xinhua news agency reported.
They closed them after investigating tip-offs by web users.
The administration will strengthen efforts on regulating online information and deal with tip-offs in a timely manner.
The Cyberspace Administration of China(CAC)said last week it had closed 50 websites and social media accounts for violations ranging from pornography to "publishing political news without a permit".
In September, the cyberspace watchdog had closed nearly 1.8 million accounts on social networking and instant messaging services since launching an anti-pornography campaign earlier in the year.
