【正确答案】One day, through carelessness, Wang Er's wife, one of his elderly neighbours, locked herself out. Many warmhearted people came over to help, but nobody could do anything. They came to him, but he declined. The elderly woman entreated the ex-convict, "If my husband comes back, I'm sure to get a sound beating. Help me, please!" Dongbao knew her husband was very rough and often beat her. Softened up by her words, he dug out some tools, and, only after some effort, did he succeed in opening the door. All those who saw his performance were dazed and full of praises for him. To express her gratitude, Mrs. Wang bought a pack of filter cigarettes and insisted that he accept it.
