Search teams heard people calling out from within the partially submerged ship, CCTV reported. Video showed one of the rescuers who had climbed on the upside-down hull tapping a hammer and listening for a response.
CCTV said the captain and chief engineer were in police custody. The official Xinhua News Agency quoted both as saying the sink sank quickly after it was caught in a cyclone.
CCTV reported that 6 inches of rain had fallen over the last 24 hours, while local media said winds reached 80 mph at the time of the capsizing.
More than 3,000 people were involved in the search efforts as divers and rescuers searched the waters.
