Six people were killed and another is missing after a landslide caused by torrential rain in Fujian, Xinhua said yesterday.
The downpour flooded three counties around Nanping city and sent water levels in the city's rivers way above dangerous levels.
In parts of southern China, relief supplies and rescue teams have been rushed in to deal with rising waters.
The death toll in Hunan province had hit 40 and more than four million people had been affected by the deluge, Xinhua said.
More than 100,000 houses were destroyed and extensive damage was reported in 16 counties across northern and central Hunan.
No fatalities have yet been reported in Jiangxi province. An official at the provincial Civil Affairs Bureau said the Xinjiang River's water level had already climbed to 37.9 metres, from the usual 33 metres after days of heavy rain.
The water had flooded vast stretches of farmland, threatening the livelihood of 10,000 farmers, Xinhua said.
People in neighbouring Henan and Hubei provinces have been building and fortifying structures to keep water out.
In Henan province's Jingjiang city, six million people have been recruited to reinforce embankments along the Yangtze River.
The city has been hoarding stones, sandbags and straw sacks to use against rising waters.
In addition, 66 reservoirs in the province have been repaired, with 335 new floodgates constructed.
