Typhoon Fitow hit China's east coast on Monday, killing at least five people and leaving four others missing, officials said.
The storm has affected 3 million residents and officials are making preparations for the arrival of another storm, Typhoon Danas.
Typhoon Fitow forced the evacuation of more than 750,000 residents from coastal areas in Zhejiang and Fujian provinces.
Damage from the storm is estimated at more than $160 million.
Nearly 1,200 houses collapsed in Wenzhou, one of the main business centers in prosperous east China, due to the powerful winds from Fitow, China National Radio reported.
The typhoon, the 23rd to batter China this year, made landfall early Monday near Fuding, a city near the border between Zhejiang and Fujian provinces, packing winds of up to 201 kph (125 mph).
The storm is expected to weaken as it moves north, forecasters said.
The high-speed rail service in Zhejiang, Fujian and Jiangxi provinces was cancelled due to the torrential rains from the storm, while the airport in Wenzhou, one of the main air terminals in the region, cancelled at least 27 flights, officials said.
It is unusual for a typhoon to make landfall in southeast China in early October, with most storms hitting during the summer.
Typhoon Fitow is just the third storm to make landfall in the region in more than 60 years, following the pattern of Typhoon Krosa in 2007 and Typhoon Tilda in 1961.
Fitow, named after a flower native to Micronesia, arrived in southeast China just two weeks after Typhoon Usagi battered the region, killing 25 people. EFE
