At least 25 people were killed after Typhoon Usagi made landfall in southern China's Guangdong province, state media reported on Monday. The victims included people hit by debris and others who drowned.
About 226,000 people were relocated, and over 3.56 million affected after Usagi struck the province on Sunday night local time, said Xinhua, citing local authorities.
Usagi, the strongest storm to hit the Western Pacific this year, uprooted trees and caused flooding and gale force winds, state television CCTV showed.
Air and ground transportation was halted and local governments also ordered schools in 14 cities to close, CCTV said.
The typhoon also caused 7,100 houses to collapse and crippled power supplies for hundreds of thousands of homes, causing economic losses worth 3.24 billion Yuan in Guangdong, Xinhua reported.
Usagi's rain and strong winds pounded Hong Kong late on Sunday prompting some to stand in the path of the waves that crashed against the pier.
