Here is the "roof of the roof of the world" - it is located in the west of the Xizang Autonomous Region, with an average altitude of more than 4500 meters. From north to south, there are the Karakoram Mountains, the Gangdise Mountains and the the Himalayas. This is the southwestern border of our motherland - the border line stretches for over a thousand kilometers, and the famous Bangong Lake, Zhada Tulin, and Pulan Port are embedded in this land. This is the Ali region of Xizang. Here, the Party, government, army, police and civilians have built the "Great Wall" to defend the country and border. Border defense officers and soldiers, cadres and the masses, immigration management police... All border defense forces bravely shoulder the sacred mission entrusted by the Party and the people, standing tall on ice peaks and mountains, fearlessly facing difficulties and hardships, and composing touching new movements of defending the country and borders in the new era. On the occasion of the arrival of the Chinese New Year holiday, soldiers from the Zhaxigang Border Defense Company of a certain border defense regiment in the Ali Army Division hung a wishing ribbon in front of the "Advance Willow", expressing New Year's greetings (photographed on January 17, 2024). Chen Shangcai, a journalist from Xinhua News Agency, took a photo in the Ali area, more than 4500 kilometers away from Beijing. There is a heroic company named Zhaxigang Border Defense Company, which was once awarded the honorary title of "Model Company for Garrisoning the Snow Plateau" by the Central Military Commission. There is a tall and upright "advance willow" in front of the company gate, accompanying border defense officers and soldiers to defend the country and defend the border. In August 1951, Peng Qingyun, the deputy commander of the Advance Company in Tibet, led soldiers on patrol at Zhaxigang. In order to identify direction and mark the location, a "Bangong Willow" was planted here, which the Border Defense Company called the "Advance Willow". The Dianjiao area of Zhaxigang Township is truly a "forbidden zone for life". The lowest temperature in winter is over minus 40 degrees Celsius, and some duty stations have an altitude of over 5600 meters. The oxygen content is only 40% of that of the plain, and ultraviolet radiation is particularly strong. "In front of us are icebergs and mountains, behind us are the motherland and the people." Due to long-term stationed at high-altitude points, Niu Yongqiang, the acting platoon leader of Zhaxigang Border Defense Company, had dry and cracked lips and turned white, with multiple burns on his face caused by ultraviolet rays. He said, "This is the test of nature for border soldiers, and sticking to one's position and guarding the lights of every household is the best reward." The officers and soldiers of the border defense company came one after another, walked one after another, and the "advance willow" stood guard day after day, year after year, expressing the longing of the border defense officers and soldiers for the advance company, and also inspiring the Ali military and civilians to not fear hardship and take root in the plateau. Chulu Songjie Township, Zada County, is located in the vast snow capped mountains at the intersection of the Himalayas and the Gangdise Mountains. During the blizzard season, more than 2000 officials and people stood firm in the deep mountains, grazing and patrolling the border to protect the country. In Zhaxigang Township, Gaer County, Ali Prefecture, Xizang, the party, government, army, police and civilians patrol the border area (photographed on January 17, 2024). "Every time we patrol the border, we need to ride horses over three large snow capped mountains and walk in the wind and snow for 15 days. No matter how hard it is, we all have a sense of happiness in our hearts because here, the country and the family are closely connected." said Cibai Yixi, a villager from Baka Village in Songjie Township, Chulu. In recent years, the border areas have developed better and better, and people's awareness of border protection has also become stronger. No matter how difficult the road is and how crooked the ground is, every corner is left with the resounding footsteps of the border guards. At the entrance of the Zhaxigang Border Police Station, there is a "convenience wall"
