BEIJING, Sept. 7 (Xinhuanet) -- Floods unleashed by torrential rains have left at least 143 people dead and more than 50 others missing in southwest China's Sichuan Province and Chongqing Municipality.

And the Chongqing municipal government also raised 12 million yuan (1.45 million US dollars) for sheltering local residents and restoring transportation and telecommunication facilities.

    On Tuesday afternoon, a work team comprising officials from the State Flood Control and Drought Relief Headquarters and ministries of civil affairs, finance and land and resources arrived in Dazhou to guide the rescue work.

    The city so far has raised 15 million yuan (1.81 million US dollars) to "rebuild homes", but one local government official said that "we still need more financial support".

    More than 5,000 armed police have taken part into the rescue work and Zhang Jun, a 19-year-old armed police, drowned when helping several villagers evacuate from their flood-besieged houses in Chongqing.

    In the county seat of Kaixian, the floodwater has almost receded and more than 200 medical workers started a three-day disinfection for the flooded areas Tuesday. Local health department has also set up 18 stations across the county to monitor any possible outbreak of epidemic diseases.

    In addition, the county also established six medical service station to provide free treatment and medicine to local residents.

    After three-day efforts, nearly all the flood-stricken areas inKaixian had resumed electricity supply. The water supply is expected to be fully resumed on Wednesday.

    Local residents are busy cleaning their houses and the trash left in the streets. Some stores and free markets of agricultural products also opened. Vehicles of publicity circuited the county, asking the residents to pay attention to the safety use of home appliances.

    Local insurance companies have started to compensate for the losses of the insured and "those private business runners who have not bought property insurance, can enjoy a series of preferential policies, including tax reduction or exemption," said Cheng Yuanhui, the acting chief of Kaixian County.

    According to local meteorological administration, moderate rainwill continue in most areas Chongqing and some areas will see torrential rain.
