France is already advanced 1883 to this degree, and big Qing Dynasty however still the level that halt pushs in pickaback car, but regrettablly is, france is embezzled as a result of a huge sum and die in one's bed of disease of infection of more than 20000 workers dies, be forced process of break down item, cost 287 million yuan, be hit water to float (rigid loss about more than 100000000) .
