In early winter, on the plateau of eastern Tibet, cotton like white clouds float over the mountains, and the river in the valley rushes forward. In Shama Village, Chayu County, Xizang, there is a company, the Xizang Military Region Shama Border Guard Company. The predecessor of the company was the 3rd Company of the 126th Regiment of the 14th Army, born in the early stages of the War of Resistance Against Japan. In October 1951, Gao Jianxing, head of the 126 Regiment, led the company officers and soldiers to enter Shama and raised the first five-star red flag on the border of Xizang. This year marks the 74th anniversary of the peaceful liberation of Xizang and the 74th year that the Samak Border Guard Company has stationed in Samak. In 74 years, successive officers and soldiers have inherited and carried forward the old Xizang spirit and faithfully guarded the border. The four "family heirlooms" of "a history book, a tree, a flag, and a family member" bear witness to their struggle and perseverance, carrying an indelible red mark and loyalty gene. Today, let's enter the Shama Border Defense Company and listen to the officers and soldiers tell the stories behind the company's "family heirloom". A history book - the relay baton of inheriting glory - is quietly displayed in the honor room of the Shama Border Defense Company, with a notebook with a reddish brown cover. This is the company history book, the cover has faded slightly, and the edges are worn and curled. Opening the title page, the words "October 1, 1951" jumped into view, with handwriting penetrating the back of the paper. On May 23, 1951, Xizang was peacefully liberated. On October 1, 1951, after the company entered Shama, it raised the first five-star red flag on the Xizang border. The then head of the delegation, Gao Jianxing, looked at the tall and straight figures of the officers and soldiers and said proudly, "Write this historic moment into the company history!" Since then, the company history book has been opened, and every rush and persistence of the officers and soldiers has been recorded one by one: in 1954, the soldier Wang Yong braved the snow to send lost herdsmen home; In 1976, Li Jianguo returned important reconnaissance intelligence on foot during a snowstorm; In 2003, the then instructor Jiao Zhibin led the officers and soldiers to successfully deal with the sudden border situation... Page by page, line by line, became the company's "guarding archives". With the passage of time, even the history book has changed from a thin one to a thick one, and the record carrier has also been upgraded to a "paper+electronic" dual archive. Remembering yesterday's history is the key to continuing today's glory. ”Every time a new recruit goes to the platoon, the first thing they do is visit the honor room, and the first "book" they read is the platoon history book. In the Honor Room, the instructor explains the stories in the notebook page by page. New recruits need to choose a "role model story" from it, share their insights and set their border defense goals in front of the entire company. On the last weekend of each month, the company also organizes a company history story meeting, where veterans tell stories about their predecessors or their own experiences in history. On the day of the end of 2023, new recruit Liu Qinyue was moved by Li Jianguo's deeds of crossing mountains and providing intelligence. He quietly set a goal: 'I also want to write my name in Lianshi!' During Liu Qinyue's first drone flight training, the drone he controlled plunged into a pile of gravel just 30 meters into the sky, and the propeller shattered. That day, he carried the wreckage of the equipment to the honor room, savoring the profound history of the company with heart, and determined to learn from the senior members of the company and become an excellent soldier. The handwriting on the history book seems to be asking, 'Can you withstand the strong winds on the plateau?' The answer is hidden in every morning and dusk on the training ground. To improve his arm strength, Liu Qinyue tied dumbbells to his hands and practiced until his hands trembled while eating; To determine the wind speed on the plateau, he waited in a mountain depression at an altitude of 4500 meters for 3 days and recorded meteorological data; The notebook under the pillow is filled with control tips, and even in my dreams, I shout 'three degrees left deviation'. Last year, during a simulated real combat reconnaissance, the drone suddenly encountered strong airflow and lost control. Liu Qinyue followed the equipment to climb and chase on a steep slope for more than 200 meters, leaving blood marks on his knees. He still tightly guarded the storage device that stored critical data. This year, on the competition field, the cold wind carried yellow sand. Liu Qinyue tightly gripped the control handle, and the sweat in his palm soaked the equipment. He pressed the confirm button to accurately collect real-time reconnaissance data, winning key points for the company. That night, he wrote in his diary, "Every progress I made was inspired by the deeds and spirit of my predecessors in the platoon." Soon after, instructor Fan Guofu's pen fell on the platoon history book again, and the rustling sound was particularly loud in the honor room - Liu Qinyue's name was finally written into the history of the platoon. Liu Qinyue carefully picked up the company history book and looked at it again and again: In March 2025, Private Liu Qinyue worked hard and successfully launched a drone during the tactical assessment, winning a key score for the unit... "This momentum is just like Yuan Shaochuan back then! ”Sergeant Deng Yiping patted Liu Qinyue's shoulder, his tone filled with satisfaction and praise. Turning to one page of Lian's history book, corporal Yuan Shaochuan recorded his experience after he won the first place in the examination of the parallel bars one exercise class by doing 640 exercises in a row: "With the 'old Xizang spirit' to lay the foundation, and the deeds of the company's old squad leader to stake the foundation, no matter how hard the task is, it can not shake our strong will." "Lian's history book is not a 'merit book', but a 'baton'. ”Leaving the honor room, the snow capped mountains in the distance were illuminated by the setting sun. Fan Guofu said to Liu Qinyue, "Even the words in the history book may fade, but there are always people who add new brilliance to it with their youth and passion." Liu Qinyue looked at the instructor and nodded solemnly. A 'rooted tree' - a silent 'instructor' - in the early winter morning, the mist is pervasive in the eastern Tibetan Plateau. The continuous mountains are faintly visible in the clouds and mist, only the camouflage roof of the Shama outpost in the mountain valley, like a steel nail polished by time, firmly embedded in this land. Bathed in the morning sun, patrolling officers and soldiers are ready to go. Before departure, they will hold a special ceremony - a party joining ceremony for two soldiers, and the venue will be set under the "rooted tree" next to the outpost. This tree emerged from a crevice in the stone and is 51 years old. ”Chief Zhang Yan told me the story of "rooting in the tree". In 1974, the officers and soldiers of the outpost accidentally discovered a crack on a blue gray rock next to the outpost, and miraculously a small pine tree emerged from inside. At that time, the sentry general Yuan Fangzhi caressed the sapling and solemnly said to the soldiers, "Where trees can live, people can take root." From then on, this tree was named "Rooted Tree". Cold comes and summer goes, and the 'rooted tree' grows strong day by day. Nowadays, its roots are coiled and coiled in the crevices of the rocks, and its trunk, branches, and leaves are lush. Clusters of emerald green pine needles are like youthful vows, recording the stories of soldiers rooting down and growing up with trees. Trees are the shadows of people, and people are the souls of trees. The 'Rooted Tree' has also become a witness to the continuous border defense of the company's officers and soldiers. Every major festival or important event, the company will organize officers and soldiers to hold ceremonies under the 'Rooted Tree'. When the new recruits joined the company, the company organized them to come to the "Rooted Tree" and told them the story of their predecessors' hard work and entrepreneurship: in 1951, the first generation of border guards entered Shama, where there was no electricity, water, or barracks. Under the conditions of no heavy machinery or fixed living supplies, officers and soldiers rely on their hands to open barren mountains, build barracks, build high platforms, and build roads... to turn the harsh conditions into battle fortresses. Under the 'rooted tree', a renowned listener transforms into a narrator. Zhang Yan still remembers the scene when the old squad leader Wen Lixiang was telling stories to the new recruits when he first joined the company. This is the 'rooted tree' that has been with us for many years, no matter how big the storms we have experienced. From Wen Lixiang's narration, Zhang Yan seems to see the extraordinary times of the past. Otherwise, don't do it. If you want to do it, do it to the best of your ability. ”It was from then on that Zhang Yan secretly made up his mind to root himself in the crevices of this stone. The new recruits have turned into veterans, and the 'rooted tree' has become even thicker. Zhang Yan has led a succession of soldiers, many of whom have grown into backbone and taken on the heavy responsibility of guarding the border. When encountering ideological fluctuations and training slackness among officers and soldiers, the 'rooting tree' is also a silent 'instructor'. Sergeant Yang Zhou had a period of time when he couldn't muster up his energy and often used the excuse of "physical discomfort" during physical training. Zhang Yan took him to the "Rooted Tree" and pointed at it and asked, "This tree grows in the crevices of the stones. It has never complained about the poor soil and has never been afraid of storms. What about you. Since then, Yang Zhou seems to have changed into a different person. During training, he actively stood in the front row of the team. While others were resting, he continued to practice in the shooting range until his arms became sore and his workout clothes were soaked in sweat. In 2023, during the shooting competition in the Chamdo Military District, he won the championship. Standing on the podium, he remembered the "rooted tree" next to the outpost - it was this tree that made him understand the meaning of "rooted". The party joining ceremony is over, and the whistle of the patrol sounds. The swaying "rooted tree" watches as the patrol team departs far away. The officers and soldiers said that they want to work together with the "rooted tree" to root in the border of the motherland and protect this beautiful land. A five-star red flag - the "spiritual spark" passed down from generation to generation. In winter, the wind at Mira Pass is strong, blowing on the face like needles. During the patrol, Sergeant Yang Lindi leaned over to help the new recruits tighten their hat ropes. His gaze swept over the young faces in the team - just like when he arrived here in early 2015, his eyes were both excited and filled with anxiety about the unknown. Everyone, follow my footprints and don't step on the shiny ice surface. There may be a dark river below. ”After Yang Lindi instructed everyone, he took the lead in stepping onto the snow covered patrol road. The team slowly moved, and the road beneath their feet was faintly visible in the wind and snow. Arriving at a relatively gentle slope, Yang Lindi gestured for everyone to rest. Yang Xutao, who stepped onto this patrol road for the first time, approached Yang Lindi and asked, "Captain, before we set off, I saw that you went to the honor room to get a somewhat outdated national flag. What was that for?" "This national flag is a replica, and its original was left behind in 1951. ”Yang Lindi straightened his waist, took a breath of hot air in his palm, and continued to preach, "In August 1950, a strong earthquake occurred near the Mira Mountain Pass, and the original mountain path was completely destroyed. In late August 1951, the then team leader Gao Jianxing carried a national flag and set off with his team. Their mission was to arrive in Chayu County before October 1st and raise the national flag." Yang Lindi pointed to the misty valley in the distance, "At that time, there was no way out, so they had to dig holes in the cliffs, embedded iron rings as handles, and tied their bodies with hemp ropes to move forward." Yang Xutao and his comrades listened attentively and held their guns even tighter. The squad leader Deng Yiping walked over and added, "At that time, Captain Gao and his team were wearing straw shoes and carrying frozen barley cakes in their arms. When they encountered a turbulent river without a bridge, the soldiers held hands and built a 'human bridge', allowing their comrades to cross the river on their shoulders. One squad leader fell into an ice cave to protect the national flag, and when he was rescued, the national flag was still tightly wrapped in his arms..." With the belief of "people are on the flag", Captain Gao Jianxing and his officers and soldiers finally arrived in Shama Village, Chayu County on the night of September 30, 1951, after going through difficulties. On the morning of October 1st, just as the sky was beginning to brighten, Gao Jianxing raised the five-star red flag with bloodstains and patches in the Chayu River Valley. For 74 years, this national flag has carried
