After making landfall on Friday morning in southern Fujian province, where at least 400,000 people were evacuated, the storm flooded streets and toppled electric transmission towers.
More than a million households were left without power, according to the state-backed Xiamen Evening News.
The typhoon was downgraded to a tropical storm late on Friday night, China's state-owned broadcaster CCTV announced.
However a broad area encompassing the capital faces a medium-to-high risk of rainstorm disasters over the coming three days, China's national forecaster said.
"Doksuri's intensity continues to weaken but the impact is far from over," the China Meteorological Administration said, warning the public to be vigilant and avoid high-risk areas in the Beijing-Tianjin-Hebei region where localised rainfall could reach 600mm.
Fuzhou city suspended metro services on Saturday morning as subway stations remained waterlogged. The city's observatory reported a record daily precipitation of 256.6mm.
Businesses and summer school classes had also been ordered suspended and the public was urged to stay indoors.
In the city of Quanzhou by China's southern coast, authorities reported some 50 individuals sustained minor injuries. Residents shared photos on social media showing downed trees with roots fully out of the ground on Saturday morning.
Earlier in the week, the storm grazed past Taiwan's main island after hitting the Philippines, where it produced landslides and flooding, and downed trees. The storm displaced thousands and caused 41 deaths — including 27 killed when a ferry capsized.
About 20 others remained missing, including four coast guard personnel whose boat overturned while on a rescue mission in hard-hit Cagayan province, officials said on Saturday, adding that they were monitoring another approaching storm.
The tropical storm is expected to move its way farther inland in China, bringing heavy rains to the capital, Beijing.
