In order to hide people's eyes and ears, the Japanese invaders and their lackeys described the disease as a "plague" epidemic and an "act of God". They temporarily set up a greenhouse with reed mats in the south of the mine, called a "big ward", and dragged thousands of workers there to be shut up, without medical treatment, treatment, going out, visiting or supplying boiled water. "The big ward, that is, the morgue, entered the big ward and ten people and nine people died."
