More than one million people have been forced from their homes by flooding that has affected nine provinces of southern China.
The floods are the result of torrential rain over the past week. More wet weather is forecast for the coming days.
The flood waters have swept away roads, damaged bridges and wrecked homes. More than 50 people have died, state media say.
The flooding has also affected large areas of farmland, damaging crops. More rivers may burst their banks if heavy rain falls.
In the Guangxi region, officials have warned of potential rock and mudslides in mountainous areas.
China's government said it was sending disaster prevention teams to the affected regions to help local authorities weather the storm.
