Maya considered whether to reduce the load by 10 kilograms. What would the efficiency be like after the reduction?
Maya lay down, and with the help of Qinglang and Shuihua's hands as pivot points, plunged her hands into the snow and mud and finally managed to grasp Maya's hand. Red with her backpack was extraordinarily heavy, and Maya strained to pull Hong Yi up. Next came Qinglang, and the two women pulled Qinglang onto the rail track. Looking down, they could only see Shuihua crouching like a toad in the middle of the slope, unable to go up and yet unwilling to go down.
Maya said, "Hold on, wait for us."
After speaking, Maya turned to go to the train to dump coal and suddenly saw Wai holding a rope in his mouth. The rope was made of a soft blanket cut into strips and tied into knots. Maya tied one end of the rope to the rail track and threw the other end down, allowing Shuihua to climb back onto the rails with relative ease while gripping the rope.
