Some illegal organizations had their members spread the doomsday message and advocate people join the cults for safety, a notice from Shaanxi province's anti-cult office said on Friday.
Members of the illegal Almighty God cult recently took advantage of the much-hyped prophecy to hold illegal gatherings and disseminate doomsday information in the province, the notice said.
The Almighty God cult started in 1990 in Henan province. The organization requires members to surrender their property to the group.
On Dec 8, police in Huang-long county, Shaanxi, detained seven people on suspicion of disseminating information on a bus to scam passengers.
The province's anti-cult office urged people to resist the cult, which it said has seriously disturbed people's normal religious beliefs.
On Dec 13, police in Xining, capital of Qinghai province, detained 37 members of the Almighty God cult and seized a large amount of propaganda, a government release said on Saturday.
Police in the two provinces have urged people to call the 110 hotline if they witness criminal or cult activities.
