1984, Sun Guoqing was assigned to Qinghe Environmental Sanitation Department and began to purchase. This is a comfortable "good job" that many young people envy. On the other hand, Sun Guoqing is eager to get a position where he can display his ambition. She learned that the cleaning team's bridge class has a heavy task and few people, and she is determined to be a cleaner. This was a "crazy" idea at that time, and friends and relatives said that it was difficult for a girl in her twenties to find someone to sweep the road in the future. But Sun Guoqing thinks that only the sanitation department is the foothold of her career. Her idea was supported by the leaders of the Environmental Sanitation Department, and Sun Guoqing was allowed to work as a sanitation cleaner in Da Qiao Class. At that time, Qiaoban was responsible for the cleaning of Huaihai North Road. There are many people and heavy traffic, so it is difficult to clean. In addition to cleaning the road from early morning to dawn when there are few vehicles, Sun Guoqing has given up the rest time during the day and has been cleaning. As soon as there is garbage and dust, sweep it away in time and put it into work all day. She returned to work when her child was only six months old. She asked her mother-in-law to carry her child to the road without embarrassment, and breast-fed her child on the roadside. Once it was raining lightly, and the elderly mother-in-law was holding her little grandson with an umbrella. When she was near her work place, she accidentally fell down and her umbrella broke, leaving her grandparents covered in rain and mud. My mother-in-law can't help complaining. She looked at her old mother-in-law and then at her son. With tears in her eyes, she said guiltily to her mother-in-law, "Mom, it's all my fault that your old man has suffered so much. I will be doubly good to you in the future. " Mom, a few words of comfort softened her mother-in-law, but she warned her not to be exhausted. Her eyes were wet and she couldn't say a word.

Sun Guoqing never gives in to anything. During her tenure as the captain of the second cleaning team and the first cleaning team, she always rushed to the front line, went deep into the cleaning point, and worked with the workers to clear the sanitary corner and overcome difficulties. Although she became a captain, her main task was supervision and management, but she always insisted on not being full-time, being both a commander and a combatant. She goes to work and arrives at work with everyone every morning, not only sweeping her own contract area, but also assessing other people's contract areas. Everyone else is off work, and I have to carry a shovel on my shoulder and a broom in my hand, and check everywhere for sanitary corners. If it gets dirty, I'll do it at any time. One summer, Sun Guoqing found a pile of chicken intestines in front of a restaurant in an alley on Huaihai Road, with flies flying around and stinking. She shoveled with a shovel, and some of them had reached the sewer. She was afraid of blocking the sewer, so she held it with her hands. Several people present said that the lesbian was really fierce and cruel, so they squatted down to clean up with her. Although sanitation work is a bit bitter, it doesn't feel bitter if you get used to it. She thinks it's just a little more effort, as long as it can be understood and respected. On one occasion, a roadside shop dumped a pile of cinder ash on the freshly cleaned roadside. She discussed with the shopkeeper whether she could cooperate and ask the garbage truck to pour it when passing by. The shopkeeper said, you street sweeper, teach me a lesson! As she spoke, she hit her, and her face was swollen. Later, the media intervened to report the matter, and the city leaders also gave instructions to ask for a serious investigation. Finally, the shopkeeper who hit her also apologized to her, which strengthened her determination and confidence in doing a good job in sanitation.

From June, 5438 to February, 2004, when cleaning the sewage pool in Huaigang, she and more than 40 sanitation workers jumped into the sewage pool with a depth of 12 meters, threw it up with a shovel and lifted it bucket by bucket, clearing out more than 200 tons of muck, which won unanimous praise from leaders and workers in Huaigang and was praised as ". As long as someone praises sanitation workers at ordinary times, Sun Guoqing is particularly pleased. Sun Guoqing actively takes the lead in his work, sets an example, and cares and considerate his colleagues everywhere in his life. One day in April, 2002, it was raining all the time while cleaning up the garbage accumulated in Qin Yi Garden. Sun Guoqing took off her raincoat for her colleagues to wear, but she caught a cold and had a fever after being caught in the rain. In the afternoon, she continued to lead the cleaning staff to shovel the ground with a shovel, and dragged it by hand when the shovel could not move. Comrades advised her to have a rest, and she said it didn't matter. This ailment is nothing. Everyone is doing it. How can I rest? After a whole day's efforts, more than 20 flatbed cars were cleared of garbage and sundries.
