Rainstorms in Guangdong have affected 800,000 people since Wednesday, and 16 national highways have been closed because of the downpour, Xinhua quoted the National Commission for Disaster Reduction's statement.
At least 447,000 were displaced while 25,000 houses collapsed, the statement said.
The continuous rainfall has also led to floods in mountainous areas and raised the water level of rivers, the statement added.
