是这个吗？Excuse me. You’re sitting in my seat.The train to Beijing! Lin often dreamed about the train, and about going to the capital.Now it was in front of him, to set off soon. He looked at his brother. “Don’t forget where you come from, little brother,” Jin said. “And watch your bags carefully.”Lin nodded, unable to speak. This was his first long trip by train at the start of his new life, leaving his village and his home for the last 16 years.He held Jin in his arms. With tears in his eyes, Jin pushed Lin away. “Go, brother. Write to us as soon as you get there, OK?”Lin jumped onto the train. There were people and bags everywhere.. He pushed past them towards his seat.A young man was sitting in Lin’s seat. He was wearing jeans and a very smart jacket, and was smoking a cigarette.What should he do? Six pairs of eyes looked at Lin, while the man looked out of the window. “Sir, you’re sitting in my seat,” Lin said, with a nervous smile. The other people watched with interest. The man didn’t turn to look at Lin, but just looked out of the window.“Excuse me. I have a ticket with the number of the seat you’re sitting in!” Lin said in a strong voice.” I also have a ticket with that number though it is in another car. Besides, I was here first, said the man, without moving his head. Though he was sitting, he looked very tall and strong. Lin looked at the other passengers for help. “But….” he started to say. “but what?” the man turned and looked at Lin. “I’m not moving.” Finally a man wearing glasses spoke in a loud voice. “This young man has the right ticket for the seat. You should move.”Lin felt brave. “See? Please move. I’ve got a long way to go.” “How long?” the young man asked.“To the last stop, Beijing.”“I’m getting off before you. Then you can get my seat.”“Where is that?” asked Lin.“Hangzhou.”Lin thought Hangzhou was far away.“It’s seven hours away from here,” the man with glasses said. “Even if it’s only 10 minutes, you should move.”Slowly the young man stood up, dropped his cigarette on the floor, and disappeared down the train.
