Torrential rain in southern and eastern China has killed at least 50 people in the past week and left 4,000 stranded, state media said on Wednesday, a fortnight after a big earthquake rattled Sichuan province. The poor and remote south-western province of Guizhou has been hardest hit, with 36 dead and another 14 missing, the official Xinhua news agency said. "Tents, quilts and clothes have been sent to Wangmo County in Guizhou, which has been severely hit by rain and floods," it added.
