Some 22 buildings have collapsed in a landslide at an industrial park in the southern Chinese city of Shenzhen, BBC reported.
About 900 people have been evacuated, with four people pulled alive from rubble with minor or no injuries, the local government said, according to the report.
No fatalities have been reported.
Shenzhen's fire brigade said it was working to free other trapped people. At least 27 remain missing. Two workers' dormitories are reported to be among the affected buildings.
An area of 20,000 sq m was covered with soil, the Public Security Bureau's firefighting bureau said.
Deputy chief of Shenzhen's public security bureau told state broadcaster CCTV that most people had been moved to safety before the landslide hit.
