Nearly 38,000 people have been relocated.In neighbouring Hunan province, a mudslide killed five people and left another four missing on Saturday. Days of heavy rain have raised the water level of the central region's Xiangjiang river, Xinhua reported on Sunday.More than 300,000 people have been evacuated across Hunan, which has lost 295,000 hectares of crops and seen more than 6,000 homes destroyed.Last week, authorities said flooding had left 10 people dead in southwest Guizhou province, which also borders Hunan, since June 22.These more recent floods come after a huge landslide triggered by heavy rain hit Xinmo village in southwest Sichuan province last month, killing at least 10 and leaving 73 missing.
