The "Beijing Morning Post" referred to the websites as "unhealthy," a word describing a broad range of illegal content such as pornography, excessive violence, and sensitive political issues.
Beijing has stepped up its policing of the Internet in recent months.
In September, the government announced revised Internet rules that require Internet operators to re-register their news sites. The regulations police them for content that can harm national security and unity, instigate demonstrations, or disturb social order.
