Typhoon Chan-hom has been downgraded and is weakening as it moves inland over eastern China after drenching the coast with more than 10 centimeters (almost 4 inches) of rain.
More than 1 million people in Zhejiang and Jiangsu provinces were evacuated and 30,000 ships were ordered to return to port. One resident who stayed behind said the wind was powerful enough to blow the rain through a closed window.
Chinese officials said this might be the strongest storm to strike the east since the Communists seized power in 1949.
Despite the fierce weather, no deaths or injuries have been reported.
Chan-hom struck China after hitting southern Japan and the northern Philippines.
This was the second powerful storm to make landfall in China in recent days. Typhoon Linfa hit China's southern Guangdong province on Thursday but quickly lost its strength.
