Survivors said houses built on the hillside collapsed like a deck of cards. Three days after the flash flood, rescue workers in Guiyang, capital of Guizhou province, were still sifting through the debris. 'We have to try our best before the next torrential rain comes within days,' said a rescue worker. Twenty-five people died in their sleep in the most seriously affected Yunyang district of the city when the mudslide came at daybreak on Tuesday and uprooted their flimsy houses built on the hillside. The residential area lies near the north railway station of the city where most low-income families live. Most of their houses were built with bricks and tiles and some were just shelters covered with planks. 'Non-stop rain began to pour down on us starting around 7 pm on Monday,' said Yuan Zugui , 75. 'I couldn't sleep at all during the night.' Mr Yuan, whose three-storey house is built in the foothills, said he witnessed the worst sight of his life when he opened the door to find out what the noise was. 'Houses collapsed and were rolling down from the hill and the debris hit my house. What am I going to do?' He said dozens of houses were levelled within minutes. He believed many of his neighbours were buried underneath the mud. People who escaped the mudslide said rescue workers and neighbours hurried to pull out the injured and dead from the debris in the rain. Ambulances were unable to reach the site so rescuers had to carry victims to hospital. Yesterday, 19 people, mainly suffering from fractures and brain damage, were still struggling for life in the Red Cross Hospital in Yunyang. Nurses said many of the victims had recounted their ordeals as they arrived at the hospital. One nurse, pointing to Li Guangxiu , one of the survivors, said: 'She refused to eat for two days, just weeping on the bed because she couldn't move.' After undergoing surgery, the 30-year-old woman was told that she had lost her husband and three children. Hospital chief Mo Yuanguang said the hospital had adequate medical supplies at the moment but would not guarantee enough supplies in the event of another disaster.
