We though a long time but we still did not know how to let the wire to get through the pipe. Finally, I have an idea." The young man said again: "I went to a store to buy two mice, one was male and another was female. I tied the wire with a line together, and tied it on the foot of the male mouse, then I put the male mouse on the side of the pipe; and then, I asked my colleagues put the female mouse on the other side of the pipe, they played with the female mouse so that she cried, when the male mouse heard the cry of the female mouse, he would ran along the pipe to save her. So he dragged the wire away to the other side of the pipe, and we installed the new wire favoring."
