The deep winter at the northernmost point of the motherland's territory seems to be frozen by the extreme cold of the Greater Khingan Range. However, the officers and soldiers of a certain unit stationed here, with their passionate youth, carved the flow of time, love in their hearts, and vows of perseverance in the frozen snow. They are stationed at three scattered outposts deep in the forest, guarding an information lifeline that stretches for hundreds of kilometers. In winter here, splashing water turns into ice, and blowing air turns into frost. What is more resilient than severe cold is faith; What is even broader than the forest is emotions. The soldiers will record the story of guarding the sentry on one wall of the sentry post. This is an ordinary wall, but it is no longer ordinary due to the smiling faces, handmade paintings, and white birch bookmarks of the soldiers. On the wall, there are smiles blooming in the icy snow, collages of love accumulated from ordinary years, and echoes of vows engraved in the rings of time. Every photo, every picture, every bookmark is a footnote to youth, a mark of loyalty, and a vivid portrayal of the spiritual world of officers and soldiers. Cold cannot freeze warmth, loneliness cannot seal love. The officers and soldiers have used the simplest way to turn the words "family and country" into small moments of growth and footprints of patrol. A wall is a mirror, reflecting growth and responsibility; It is a boundary marker that marks perseverance and inheritance; It is also a window to tell the world that although the sentry is unknown, the hearts of the sentry officers and soldiers are sincere and burning. Today, let's walk into three snow covered forest outposts, listen to their stories of perseverance, and appreciate their unwavering beliefs. The 'smiling face wall' is located at the outpost, where every defense and harvest is worth seeing. At the end of the corridor at a certain outpost, there is a 'smiling face wall' covered with photos. The shining moments of the officers and soldiers' training and life converge together, making this the warmest corner of the company. Private Song Xinliang carefully posted a new photo of himself: his eyelashes were frosted, his nose was red, but the corners of his mouth were struggling to rise. This is his appearance when he connected the optical cable for the first time in extremely cold weather after being disconnected. This new recruit from Fujian once yearned for the poetic snow scenery of the northern country, until he experienced the "splashing water into ice" and his fingers froze stiff, only then did he understand the severe cold and hardships here. On his first patrol, the snow was knee deep and he walked with his legs covered in lead. The class monitor encouraged in front, 'Just walk a few more times and you'll save up your strength.' Song Xinliang looked at the back of the class monitor ahead and gritted his teeth, persevering until the end. The task was completed, and looking at himself in the photo with a frosty face but a smile on his face, he suddenly felt a sense of security: "This is the ice flower condensed from sweat, the sweetness tasted after bitterness." Second level Sergeant Wang didn't say much, but his smile left a deep impression. In the photo, he was covered in oil stains as he lifted the newly repaired circuit board in the computer room, smiling brightly. Before that training, the key equipment suddenly collapsed and spare parts couldn't be transported in. Wang Chuang plunged into the computer room and traced each wire one by one, measuring each node one by one. At dawn, when the indicator lights turned green in unison, this usually calm veteran couldn't help but clench his fists and laugh out loud, "Being able to withstand the critical moment is our greatest sense of achievement." Beside Sergeant Wang Xilong's photo, there was also a commemorative photo of him holding the promotion order. Last summer, the platoon leader recommended him to independently carry out communication support exercises. Months later, he successfully completed the task and stayed in the team with excellent qualities... In that photo, his smile is full of confidence and sunshine. Sergeant Ren Chaofan's smile froze in the spotlight of the stage - he held the microphone, sang high with his head up, and his expression was devoted. This shy soldier, representing the company, stepped onto the stage of the "Northern Xinjiang Voice" competition organized by the higher authorities. As the melody of the original song "Overwatch the Frontier" played, scenes of Yukino patrolling the line and the figures of his comrades helping each other came to mind one after another. After returning from the competition, he put this honor on the "smiling face wall": "At the outpost, every defense and every harvest is worth seeing." There is also a special "cloud photo" on the wall - First Class Sergeant Ding Ao and his wife and daughter looking at each other across the screen, with a warm smile on their faces. My wife came to the team for the first time, touching Ding Ao's cracked hands and shedding tears of heartache. Ding Ao brought his wife to the "Smiling Face Wall". When she saw the scene of the family "reuniting across the sky", she picked up her pen and wrote a message: "As far as your battlefield is, as long as my watch is." On the "Smiling Face Wall", there are not only smiling faces, but also the backs of people climbing mountains in the wind and snow, the silhouettes of poles carrying wires in the wind and rain, and the silhouettes of roads paved under the sunset; Some comrades even wrote "little notes": "On the day you received the award, I was also on site" "This road was paved by us together"... Among the "little notes", the "comment" of the sentry commander was the most affectionate: "The coldest ice cannot freeze the warmest smile. The farthest sentry has a firm watch at all times. The smile here is a resounding answer - we root in the sentry post and grow in the harvest!" "Grain Painting Wall" seeds come from the earth, just like the soldiers' perseverance, ordinary but tenacious. Walking into a certain sentry post, the "Grain Painting Wall" made of grain collages is unique and ingenious. Red sorghum, yellow millet, black beans, white rice... These ordinary grains, in the hands of officers and soldiers, turn into vivid pictures that record the life of the sentry. The initiator of the idea of "painting with grains" is Second Class Sergeant Liu Xun. Many years ago, inspired by the traditional technique of "grain painting" in the stationed area, he led his comrades to try using this method to record what they thought and saw in their hearts, in order to add color to the long winter. The first work - the company logo, was repeatedly pasted by the officers and soldiers. Round beans are difficult to fix, requiring more than ten processes that not only test eyesight but also sharpen the heart. Since then, creation has also become a form of "training": this unique creative process unexpectedly hones the patience and meticulousness of officers and soldiers, and develops more stable control at the fingertips. During a patrol, Liu Xun and Private Liu Xiangrong were about to connect precision optical fibers in the wind and snow, but their efforts were in vain with just a shake of their hands. He encouraged Liu Xiangrong: 'Don't be nervous, just like when you usually create' grain paintings'... 'That day, Liu Xiangrong completed the wiring task independently for the first time. Snow fell on his shoulder, and Liu Xun's smile was particularly warm. On the wall where the sentry was stationed, dozens of works have now "grown": snow sea patrol, tower operation, collective celebration... The latest one is called "Forest Sea Arteries". In the picture, officers and soldiers use black rice to pave patrol routes, and miscellaneous grains are pieced together to form figures; A striking 'silver thread' is made up of transparent glutinous rice pieced together one by one. Liu Xun said that the inspiration for this painting came from a difficult repair during a snowstorm. The signal suddenly interrupted that day, and everyone braved the wind and snow to find the breakpoint and complete the maintenance. When the signal was restored and several people hugged each other in the wind and snow, Liu Xun was determined to "plant" this long road carrying the mission on the wall. This wall not only records history, but also soothes the soul and expresses emotions. Newcomer Wang Xiaochuan often misses home, and Liu Xun gives him some advice by depicting his hometown on the wall. Wang Xiaochuan's parents specially sent rice from his hometown, and he used his spare time to describe his worries little by little - in front of the smoking farmhouse, a small river meanders. The hometown that I have been longing for day and night has been hung on the wall of the outpost. ”Every time he returns from his patrol and sees the "hometown" hanging on the wall, Wang Xiaochuan's heart is always calm and warm. The heart is at the outpost, and the outpost is the 'home'. Liu Xun also mobilized his comrades to send grain seeds from all over the world and created a "concentric circle" - each comrade used the seeds from their hometown to spell out a "heart", and everyone's "heart" gathered into a larger "concentric circle". In Liu Xun's view, this "heart" tells the common wish of the officers and soldiers: to root together at the outpost and watch over the mountains and rivers of the motherland with one heart. After a snowstorm, sunlight filtered through the window frames and shone on the "concentric circles" of the "Grain Painting Wall". Officers and soldiers use their emotions and love to create aspirations and expectations, just as Liu Xun wrote in his diary: seeds come from the earth, just like the soldiers' perseverance, ordinary yet resilient. The 'Bookmark Wall' believes in the power of dreams. Wherever youth takes root, dreams bloom on the walls of study rooms at certain checkpoints, with bookmarks made from birch bark hanging one by one. The officers and soldiers washed and polished the bark of the trees, using knives as pens to carve their own "heart language". White birch is a pioneer tree in the Greater Khingan Range, known for its cold and drought resistance, as well as its tenacious growth. The sentry post has always had a tradition of picking up bark and making bookmarks. The varying depths of the marks are like branding dreams and vows into the texture of trees, witnessing the years of perseverance in the forest. On the bookmark of First Class Sergeant Wang Zexin, there are two words engraved: "Return to Zero". This is his inner monologue after breaking two consecutive records in the superior martial arts competition. On the second day of winning the championship, Wang Zexin engraved this bookmark. Honor belongs to yesterday. Once the task is completed, it is a new starting point. "From that day on, he diligently practiced troubleshooting with his" sharp eyes ", accompanied by equipment all day long, carefully recording various data and maintenance cases, and embarked on a path of constantly challenging himself to upgrade his abilities. On another bookmark on the wall, engraved with the words "Stable and Steady", the signature is driver and first grade sergeant Cai Yi. Turning the clock back to a cold winter, Cai Yi encountered a sudden "wind blowing snow" while carrying out his mission. He rolled down the car window and leaned forward to identify the road that was almost buried in snow, with snow particles hitting his face like knife cuts. With his' muscle memory 'of every turn and slope, Cai Yi calmly controls the steering wheel and drives on the' life and death line 'until the sentry post lights penetrate the snow curtain. No matter how strong the wind and snow are, the beam of light in my heart cannot be extinguished. ”This bookmark records the veteran's perseverance in the wind and snow. "The road conditions are unpredictable, and the outpost is an eternal destination. For a driver, arriving is a mission and a faith." On this wall, there is also a "seed bookmark" - a farewell message left by veteran Li Zhongwei to his comrades. That winter, the new equipment testing encountered a technical bottleneck, and Li Zhongwei led the backbone to fight fiercely for several days. Before leaving the team, he handed over all the technical manuals he had written to his comrades and found a piece of birch bark with a straight texture, engraved with the word "seed". He said to his comrades, "With updated equipment, personnel changes, and a willingness to study and overcome challenges, we must stay at the outpost like seeds, take root and sprout." Now, this bookmark is treasured by the outpost. Every year when new recruits arrive at the outpost, they can always hear the story of this' seed bookmark '. Believe in the power of dreams, where youth takes root, dreams bloom. At the outpost, more bookmark stories are being written - Zhang Jianhui, Cai Yi's apprentice and pilot, performed outstandingly in the mission last year. When he was awarded the "Four Haves" Excellent Soldier Certificate, he carved a "Forward" bookmark; Sergeant Ma Guolong, who had been on the job for over a year, won the first place in a professional martial arts competition and carved a "transcendence" bookmark; Second level Sergeant Zhao Fu innovated the fault detection technology and quickly located equipment faults. After that, he carved a "Jingwei" bookmark... The morning light once again illuminated these three walls. The warmth on the "smiling face wall", the splendor on the "grain painting wall", and the dreams on the "bookmark wall" - they stand quietly in the depths of the forest, recording the soldiers' daily perseverance. Here, every wall is a mirror, reflecting the sincerity and love in the extremely cold outpost, the sunshine and warmth in the hearts of the officers and soldiers, allowing youth to take root in the wind and snow, and passing on the mission through perseverance.
