To prevent raids, "leaders" are banned from having mobile phones and are driven to places where they "preach their religion." Gatherings only allow a maximum of seven people to avoid attracting attention from the authorities, the report said.
The cult persuades followers to quit their jobs, give up everything they own, and break off all contact with relatives.
An online "anti-Almighty God" alliance said millions of people, especially rural residents, had become its victims.
Wang Xiaomin, a 48-year-old villager in Henan with little education, said she started believing in the cult in 2005 because one of her former classmates had told her the world was about to suffer a major disaster.
Wang said she left home in 2008 to spread the word in Xinmi City in Henan, raising nearly 600,000 yuan (US$96,000) for the cult.
Police have called for public tip-offs to crack down on the cult as it was believed more people would be taken in as December 21 approached. That's the day some people believe the world will end according to a Mayan prophesy.
On December 9, three women and a man were detained for promoting "Almighty God" on the streets of Fuzhou, capital of southeast Fujian Province.
They distributed leaflets saying doomsday was near and only those who joined their cult would survive. They handed out red dates and walnuts as their Chinese pronunciations sound like "escape in time."
They also invited people to write down their names, phone numbers and home addresses on a "Life Book" to join the cult.
