Rotating the nut, removing the shell, cleaning the oil, manual winding, sand blasting, reassembly... With a symbolic smile, the girl in the video repaired the diesel engine, engine and chain saw. Soon, these "heavy guys" who may be older than her took on a new look. Her name is Lin Guoer. She is a short video blogger. The picture shows Lin Guoer shooting a video of repairing equipment. (Ding ningwen / picture of Xinhuanet) Mechanical maintenance, electric welding, carpentry, bricklayer... With strong hands-on ability, Lin Guoer quickly sucked more than 6 million powder on the short video platform and won tens of millions of praise. "Winding madness", "mechanical Magnolia", "ruthless iron hand" and "Yunnan little Luban"... The beauty of labor, boldness, craftsmanship and courage to break through and fight are the "high-frequency words" you feel after watching her video.

"Did she really repair these instruments herself?" A series of onlookers and questions also poured in. With such questions, Xinhua reporter visited Lin Guoer on the spot.

Walking deep down the mountain road, you can see a place with wooden houses, running water and fields. The workbench that often appears in the video is somewhat shabby. Two cameras for shooting short videos stand there, and the paint has fallen off. "This is the venue I rented. I built these cabins myself. I want to build a dream paradise with my own hands!" Lin Guoer explained. The picture shows an aerial photograph of Yanjin County.

She chose to wear a sweater in yellow, "the bright color is more white and energetic!" There are some wounds and wet paint on her hand, which are the marks of "fighting" with steel. (photographed by Ding Ning of Xinhuanet) In 2017, Lin Guoer graduated from Kunming University majoring in water conservancy and Hydropower Engineering and began to engage in short video creation in 2018. At first, the generator was repaired in order to power up the shooting base. Inadvertently, the repair process was posted online and received a lot of attention. Slowly, she began to help villagers repair household and agricultural equipment, and netizens from all over the country will send waste equipment to "test her". The picture shows Lin Guoer repairing the motor of the flour mill for the villagers. (photographed by Ding Ning of Xinhuanet) Dismantle, close, renovate... Usually a seven to eight minute video needs to shoot more than 200 shots, which can take more than ten hours a day. If the test machine is not successful after repair, it has to be disassembled for inspection and repair. In case of "jam", you should check the Internet and ask the master in the town. At the beginning of shooting, the time cost was greater. Today's skilled technology has been repeatedly tested and practiced by Lin Guoer. The picture shows Lin Guoer's manual winding. (photographed by Ding Ning of Xinhuanet) On the short video platform, Lin Guoer's video update speed is not fast, and the video duration is not short, but the video completion rate is very high, and there are many "iron powder" urging the update. Many netizens said that watching such a detailed repair process has a solid sense of healing and makes people feel decompressed. The picture shows Lin Guoer offline the motor of the flour mill.

(photographed by Ding Ning of Xinhuanet) After graduating from University, Lin Guoer sent resumes to the construction site and hydropower station, and finally the stone sank into the sea. She worked as a clerk and passed the civil service examination. As a child in the village, she has a strong nostalgia for her hometown. Finally, she decided to go back to her hometown, build her own base, combine the style and technology of her hometown, and build a hometown she understands and misses through short videos. "After that, I want to shoot more videos showing my hometown." Lin Guoer said. The figure shows the wiring of Lin Guoer's motor centrifugal switch of flour mill. (photographed by Liu Dong of Xinhuanet) Lin Guoer is a rare college student in the village. The villagers have high hopes for her. In the eyes of her hometown, she should "stay in the city and do more mental work!" She thinks that she "doesn't do business" with waste machines every day. But she didn't think so, "as long as you dare to think and work hard, you can do something in your hometown!" The picture shows Lin Guoer as a repaired motor assembly part of the flour mill. (photographed by Ding Ning of Xinhuanet) She steadily exported her works and gradually "gained a little reputation" in her hometown. The villagers also slowly accepted what she did. When the sewage treatment pump of the town hospital and the agricultural equipment of the villagers broke down, they would come to her for help. "It's exciting to see me! Electric welding is so exciting! I especially enjoy the process of assembling parts." In the face of a pile of old instruments, Lin Guoer's eyes flashed a bit of surprise and began to start immediately. The picture shows that the repaired flour mill motor grinds corn flour again and the test run is successful.

(photographed by Ding Ning of Xinhuanet) In the interview, Lin Guoer is always full of passion, bouncing and showing great vitality. After shooting short videos and finding what she really loves, she became more and more confident. "I'm more and more laughing in the fan comment video, and I'm particularly gratified." The picture shows Lin Guoer playing with her adopted dog. (photographed by Ding Ning of Xinhuanet) The day before the arrival of the reporter, Lin Guoer had just been interviewed by three media. "We often add wechat of many people at the end of the day, including the media, teams and fans who want to cooperate." However, Lin Guo'er is surprisingly calm about these popularity. She knows that the pursuit from the Internet is a temporary noise after all. She refused a lot of exposure opportunities. "I always feel sorry that I haven't done anything practical. I still need to precipitate and learn." The picture shows the parts table of Lin Guoer's repair equipment. (photographed by Ding Ning of Xinhuanet) "My hometown has high mountains and deep valleys and backward economy. Many young people are unwilling to come back. I want to promote my hometown by shooting short videos and sell some agricultural products of my hometown, so as to make my hometown richer and more lively." Lin Guoer knows that her strength is very small, but she is full of confidence in the future because she is not afraid of hardship and fatigue. In the eyes of others, this is the story of a young girl returning home to start a business by taking the "wind of short video", but for herself, she found a stage in her hometown and became a more confident and beautiful herself.
