On October 9, police officer Liu Liwen of the Ouyang Road Police Station of the Hongkou Public Security Bureau celebrated his 60th birthday. As he bids farewell to the police camp and the community where he has worked for 27 years, he will enter retirement life.

Liu Liwen’s outstanding performance at work once won him the title of “National Outstanding People’s Policeman”.The most proud work of his police career is undoubtedly the anti-theft door at the door of various major districts in Shanghai. revolving door.

October 8 is the last day of the National Day holiday and Liu Liwen’s last day at work. On this special day, Liu Liwen, who could have enjoyed vacation benefits, did not take a break. He put on his police uniform again and completed his last shift with the \”comrades\” who had spent time together day and night.

The most \”iron\” comrade

Yesterday morning, Liu LiwenCarrying a small can of lubricating oil, I came to the door of No. 23 Dalian West Road. After joining the public security force in 1993, Liu Liwen first worked as a patrol policeman, and in 1995 he began to work as a community policeman at Ouyang Road Police Station. The Xingfu Village community to which No. 23 Dalian West Road belongs is the first community under Liu Liwen\’s jurisdiction after he became a community policeman. There is one of his \”old comrades\” here.

This comrade is now \”23 years old\”. For 23 years, no matter the wind or rain, it has always stood at the entrance and exit of No. 23 Dalian West Road, protecting the property safety of residents in the community, and its \”brothers and sisters\” have spread all over the country. It is Liu Liwen’s prevention invention-the revolving iron door.

Back then, Liu Liwen, who was newly appointed as a community police officer in Xingfu Village Community, was troubled by the high incidence of bicycle thefts in the community. At that time, there were 6 entrances and exits in the community.It was obviously not feasible to arrange security guards at each entrance. Blocking the exits would bring inconvenience to the residents. Once, Liu Liwen attended a friend\’s wedding banquet and saw that his son really liked playing with the hotel\’s revolving door and almost got stuck. This gave him inspiration: If this kind of door is used in residential areas, can it prevent thieves from stealing large items?

He drew design sketches overnight and coordinated the production of co-construction units. In 1997, Shanghai’s first four-leaf community security revolving door was erected at the entrance of No. 23 Dalian West Road. A few days later, a thief who stole a large bag of belongings was trapped. The street quickly installed nearly 300 such revolving iron doors in various communities. Liu Liwen\’s invention was awarded the Prevention Creation and Invention Award by the Shanghai Public Security Bureau. Later, Liu Liwen also made small inventions such as window anti-theft bolts and electric vehicle battery anti-theft locks. From this, he became known as \”Police Camp Luban\”.

The revolving iron door has always been Liu Liwen\’s most proud work. Whenever he has free time, he will bring tools and lubricants to inspect the first iron door he designed. This 23-year guard resident \”old comrades\” for property security. He knows that as the construction of smart public security continues to advance, revolving iron gates will eventually disappear from the stage of history.

The most enthusiastic comrade

Zijing Garden Community is a residential community that Liu Liwen has worked hard for more than ten years. Here is a group of his closest comrades.

\”Officer Liu, haven\’t you retired? Why are you still coming to Bauhinia?\” \”It\’s the last day today, Aunt Chen.\”As soon as Liu Liwen walked into the community, many residents They gathered around.

\”Officer Liu, my wife has quarreled with me again.\” \”Officer Liu, there have been a lot of strange young people upstairs in the past two days. Could it be that they are renting in a group?\” \”Officer Liu, your anti-theft bolt Is there any more? I’ll install one for my parents’ house.” The residents were all talking, Liu Li.Wen immediately took out the notepad he carried with him and wrote down everything.

Most of the residents in the Bauhinia Garden Community are elderly people over 60 years old, and there are 70 or 80 households with elderly people living alone. Visiting these elderly people living alone is part of Liu Liwen\’s daily work. On the last shift, of course I have to go see them.

Liu Liwen went to the neighborhood committee and took a police-citizen contact card from the drawer, took the elevator to the ninth floor, and knocked on Grandma Jin’s door. But his steps were obviously a bit awkward. heavy. In 2010, when he first became a police officer in the Bauhinia Garden community, Liu Liwen visited Grandma Jin’s home and learned that her husband, Mr. Meng, had been bedridden due to illness and that her son was abroad, so he bathed his wife and shaved his head to become Grandma Jin. The biggest trouble. Liu Liwen immediately contacted the bathhouses and barber shops in the area to provide door-to-door services for the elderly, and left his mobile phone number with Grandma Jin.

In the next 10 years, it became Liu Liwen\’s job to take Elder Meng to see a doctor, change a light bulb for Grandma Jin, and help the second elder to clean. This touching feeling made Grandma Jin regard Liu Liwen as her own son, and she would always think of Liu Liwen first when something happened. After Mr. Meng passed away two years ago, Grandma Jin’s physical condition was not as good as before, and her memory began to blur. She was afraid that she would not remember Liu Liwen’s phone number, so she often asked Liu Liwen for the police and citizen contact card, plus What I brought today, there are already 6 police and citizen contact cards sandwiched under the glass of Grandma Jin’s dining table.

When the old man learned that Liu Liwen was retiring tomorrow, his eyes suddenly became moist. \”Don\’t worry, I will still come here often after retirement.\” Holding the old man\’s hand, Liu Liwen also had tears in his eyes. The thing that worried him most about the Bauhinia Garden was the gold medal. Grandma.

Being rooted in the community and giving sincerely will be rewarded with sincere treatment from every resident. Liu Liwen said that everyone is his informant and intelligence agent. He can learn from the residents immediately about all the big and small things in the community, so that he can solve the problems in time, eliminate hidden dangers, and ensure the safety of the community. “The construction of a safe community requires comrades who walk side by side—these enthusiastic residents.”

Hand over the baton

Back at the police station, young police officer Zhang Haining was helping Liu Liwen organize his desk. Liu Liwen explained to him one by one what he had just written in his notes. Police officer Zhang is born in the 1980s. He is not only Liu Liwen\’s close disciple, but also the \”successor\” of Bauhinia Garden.

A few months ago, the police station leader asked Liu Liwen to choose an apprentice among the young policemen. Liu Liwen fell in love with this young man who had the same military experience as him at a glance.

At first, Zhang Haining felt that Master was an outstanding people\’s policeman in the country and naturally had unique \”know-how\”. As long as he learned these know-hows, all difficulties would be solved. But after several months of follow-up work, the master only led him to do one thing—visiting residents door to door. Every time he visits a household, Liu Liwen will ask Xiao Zhang to write down the needs of the residents, even if they are trivial and trivial.

After a few months, I haven\’t learned the \”tricks\” and the work manual is already full. During the renovation of the community monitoring equipment, Liu Liwen and Xiao Zhang visited every corner of the community, even the green belt, for fear of missing any surveillance blind spot. During that period, Xiao Zhang’s number of steps every day ranked among the top in his circle of friends.

Xiao Zhang later couldn’t help but ask the master what special skills he had to keep the bottom of the box. Liu Liwen pointed to the work manual and said: “It’s all here. It is your most reliable comrade.” Xiao Zhang didn’t understand it at the time, but by chance, he discovered a thick stack of notepads on his master’s desk, which contained all kinds of trivial matters recorded by the residents in the jurisdiction. Only then did Zhang Haining realize that Master had been telling him thatthere are no shortcuts in community work. The only \”trick\” is to take every issue of the residents into consideration and do it seriously.

Zhang Haining helped Master compile 16 work manuals. \”It\’s all old content. You can deal with it as you see fit.\” Faced with the master\’s instructions, Xiao Zhang held up the work manuals and stored them one by one in his desk.

\”I believe that Xiao Zhang will definitely do better than me.\” Liu Liwen is quite reluctant to say goodbye to his position as a police officer after 27 years of hard work, but he also believes thatFull of heart, \”My young colleagues are flexible, have ideas and are willing to endure hardships. Under their protection, Shanghai will definitely be safer.\”
