Days of heavy rains have left many parts of Guangzhou, capital of South China's Guangdong province, under water on Tuesday.

The downpour has flooded many subway stations and turned several tunnels into underground streams. On some road sections the water level was reportedly as high as one meter.

Municipal employees and other government launched a cleanup operation to drain the flooded areas.

Some local residents blamed the bad drainage system for the flooding. They said the existing system is unable to meet the growing demands of the city.
