In 1942, Hu Tiejun was a transport soldier in the Logistics Department of the Eighth Route Army, responsible for delivering ammunition and medicine to the front line. He had no chance to go to the front line to kill the enemy, so he drove a donkey cart on the mountain road every day. Once while delivering medicine, he was raided by the Japanese army. He hid the medicine, lured the enemy away, and wandered in the mountains all night. The medicine was delivered safely, but he had two toes amputated due to frostbite. When his comrades asked him if it was worth it, he said: "Every bullet on the front line was carried by us, and every pack of hemostatic medicine was carried on our backs. Logistics is the front line." After liberation, he worked as a commentator at the Logistics Museum and told the children: "Heroes are not all on the front line. Those who push carts, carry food, and carry stretchers are all heroes."
