Four days after mudslides swamped the region, they are still finding survivors in the Gansu province of north-western China.
The chance of finding some people still alive means the rescue teams refuse to give up hope.
More than 600 people are still missing. At least 1,100 are known to have died.
Clean drinking water is the main concern. Most local sources are knocked out or polluted. Infected injuries and the lack of sanitation increase the risk of disease.
Overnight rain brought fresh misery for survivors.
A further nine centimetres are expected in the already-saturated region on Friday.
The threat of more landslides is said to be “relatively large”.
