How did the migrant cadres in Xichuan, South-to-North Water Transfer Project die in the line of duty?

Died of illness. June 20 1 1, 16 is the day when immigrants from Baishiya Village, Shangji Town, Xichuan County moved and loaded their cars. At three o'clock in the morning, Wang Yumin arrived at the settlement 20 kilometers away by bike. At noon, the temperature is as high as 40 degrees. Wang Yumin, suffering from severe emphysema and edema, ignored the doctor's advice and went in and out to help the immigrants carry furniture, wood and food. I was too busy to have lunch until two o'clock in the afternoon. Director Wang Zhihong saw Wang Yumin's hands shaking so much that he couldn't even hold the food.
