In my memory, I will never efface the image of a common service worker.
It was last New Year when all my family members gathered together that suddenly the heating pipe broke up. The warm steam burst forth from the crack. We could do nothing but have a shot at calling the household management center. Fortunately, someone answered it and decided to send a person here.
Ten minutes later, a middle-aged man came. He quickly shut the valve, but one of his hand was hurt by a spine carelessly. Not having a rest, he replaced the broken pipe. It took him half an hour to finish replacing it. Only after that did he remember his injured hand.
In our thankful sight, he disappeared in the curtain of night. He must have been getting together with his family, but he did the job for the sake fo others convenience at this special night. What a nice man! I will never forget him.
