Mr Ling lives in China. He worked in a factory and last year he retired. His wife died five years ago and his son works in Japan. He always has sports and he is in good health.

One day his son called him and asked him to have a journey to Tokyo. He was very happy. He was afraid to travel by plane and took the ship.

On the first morning on the ship Mr Ling met an Englishman at table. The man said to him, “Good morning!” He thought the Englishman told his name to him. So he stood up and said, “Ling Bing!” And it was repeated a few mornings and Mr Ling told a teacher about it. Hearing him, the teacher began to laugh and said, “He says hello to you in the morning.”

The next morning, when Mr Ling met the Englishman, he said, “Good morning!” And the Englishman stood up and said, “Ling Bing, sir.”
