It was not difficult to see him limping to the railway and leaning down slowly, wearing a small black hat, a big black jacket and a dark blue cotton robe. But it is not easy for him to climb the platform over there when he crosses the railway. He climbed up with both hands, and his feet shrank again; His fat body leans slightly to the left, showing the appearance of hard work. At this time, I saw his back, and tears soon flowed down. I quickly dried my tears. I'm afraid he will see it, and I'm afraid others will see it. When I looked out again, he had come back with the bright red orange in his arms. When crossing the railway, he first scattered oranges on the ground, climbed down slowly, and then picked them up and walked away.
