Seven people were still listed missing following the landslide triggered by heavy rain, while authorities said the continuing downpour was affecting the rescue operation.
Thirty-one bodies have been found after the massive landslide hit the construction site of the hydropower station in Taining County in Fujian Province yesterday.
Two people were pulled out alive, state-run Xinhua news agency reported.
"We were still asleep when the mountains began to jolt very strongly and before we know it, sand and mud were flowing into our room," said Deng Chunwu, who survived the landslide by hiding underneath a supporting pole along with three other people in their work camp.

"We were still asleep when the mountains began to jolt very strongly and before we know it, sand and mud are flowing into our room."
Deng added that their room has been pushed 10 metres further by the flowing mud.
Heavy rain has made rescue work more difficult, and according to Zheng Guoen, deputy head of the provincial drought and flood control office, residents in the area need to be evacuated soon to avoid more geological disasters.
Rescuers are also working to clear the roads leading to the landslide site after multiple cave-ins. Boulders, mud and twisted steel bars are scattered around the landslide site.
Sniffer dogs are working alongside over 600 rescuers to help detect any signs of life from the debris.
Authorities said precipitation in Taining is 35 per cent higher than historical average since this year. In the last 24 hours, precipitation has hit up to 215.7 mm in parts of Taining, triggering landslide.
The site under construction is an extension of the Chitan hydropower station, an affiliate of Huadian Fuxin Energy Limited Company.
The construction of the hydropower plant began in November 2015 and is expected to get operationalised in August 2017.
