Illustration: Chen Yujie is in the Xilanta Border Guard Company. When she opens the window in the morning, she can see the vast the Himalayas Mountains with many ice peaks. The platoon is built on a wide flat beach, with a nearby river flowing with snowy mountain meltwater, continuously flowing throughout the year. All of the platoon's domestic water comes from it. The company's army horses need to rush to the grassland every day to graze. That day, I followed Tibetan warrior Rob to release my horse. Because I was just learning how to ride a horse, Rob helped me choose a gentle and short black horse. Rob called it "Black Warrior". Although horses on the plateau are short, they have more endurance when climbing slopes than those on the mainland. When encountering a steep slope, as long as you grab the horse's mane and pinch your legs, the "Black Warrior" will run up the slope. Slender black mane, shining brightly in the sunlight. We drove the horse to a place near the water source and then dismounted to rest. We sat on the golden grass beach, watching the flowing clouds and the burr bushes swayed by the wind, quietly waiting for the sun to set. The grass in March and April is still thin and not abundant. From a distance, the burr clusters are sparse and sparse. Rob said that in Ali, a place with 5 grass per square meter can be called a grassland. In the distance, the military horse suddenly whined and Rob suddenly stood up, looking around. After a while, the horses regained their composure. I asked him what was wrong, and Rob lifted his dark face and stared at the continuous snow capped mountains, telling me the story of his first encounter with a pack of wolves. That summer, they went on patrol at the mountain pass. When the sun set, they had not yet reached their duty station. The soldiers had to find a mountain ditch and set up a tent on a deserted beach for the night. According to the customs of herdsmen, soldiers build a circle of stones outside the tent, which can not only prevent wind damage but also withstand attacks from wild animals. At night, stars leap into the sky, and the Milky Way shines brightly. Rob and another soldier stood at the first post, picking up some cow dung cakes and thatch, and starting a bonfire. The burning of cow dung is very quiet, emitting a scent of green grass, unlike the crackling sound of firewood and the scattered flames. In less than an hour, the class monitor came out to change posts. In the summer plateau, the cold wind is still piercing. Rob crawled into the tent, his ears filled with the sound of the strong wind hitting the tent. Just as he was about to fall asleep, a wolf howl came from the pitch black wilderness. Rob immediately crawled out of the tent and saw the squad leader searching around with a bright flashlight. In the wild, wolves will quietly lie on the ground and cannot be seen at night. The squad leader is also a Tibetan warrior. He follows the direction of the wolf howl, and the flashlight slowly moves back and forth towards the distance. Suddenly, a pair of eyes sparkling green appeared in the darkness. It's a pack of wolves. Judging from its location, it is approximately over 200 meters. Soon, the horses also smelled the danger and began to hiss. Most warriors are afraid when they encounter a pack of wolves for the first time. The class monitor asked Rob to call everyone up and take out a bright flashlight to shine into the wolf's eyes. Soldiers without flashlights shout with their phones, while those without anything shout loudly towards the wilderness. Rob said that these were all methods taught by his parents when he was a child. Sure enough, a pair of green eyes disappeared in the darkness, and the horses gradually quieted down. However, the soldiers still dared not sleep and patrolled around the campsite all night, fearing that the wolf pack would attack from other directions. Until dawn, he
