At least 12 people died in severe flooding Tuesday in a Chinese provincial capital that trapped people in subways and schools, washed away vehicles and stranded people in their workplaces overnight.

The already drenched city of Zhengzhou, the capital of Henan province, was hit by 20 centimeters (8 inches) of rain from 4 to 5 p.m., the official Xinhua News Agency said, citing the Henan weather agency.

The torrent of rain turned streets into rapidly flowing rivers and inundated subways stations and cars. Videos posted online showed entire neighborhoods covered in waist-deep water and vehicles floating in the muddy mire.

To the north of Zhengzhou, the famed Shaolin Temple known for its Buddhist monks' mastery of martial arts was badly hit. Henan province is home to many and a major base for industry and agriculture.

Xinhua said 12 people had died and 100,000 people had been moved to safer places.

Stranded people were spending the night in their workplaces or checked into hotels.

Wang Guirong, a 56-year-old restaurant manager, said she planned to sleep on the couch in her restaurant after being told there was no power in her neighborhood. The State Grid Zhengzhou Power Supply Co. said a downtown substation was forced to shut down because of the rain.

"I have lived in Zhengzhou all my life and have never seen such a heavy rainstorm as today," Wang said.

China experiences regular flooding during the summer, but the growth of cities and conversion of farmland into subdivisions has raised the impact of such events.
