Jenny's post happens to be a thunderstorm area. Every day when it thunders at 3 pm, the soldiers have to sit on the bed with all the electrical appliances. Thunder played one after another for two hours. At the most dangerous time, the roof of the post was blown through a hole the size of a fist. That day, thunder floated around the room like a blue ball of light the size of a football, and everyone held their breath and dared not lead it.

The patrol road of the soldiers in the post of Jennings House is not long, but it is full of danger, especially in winter. The higher the altitude, the lower the temperature, the thicker the snow and the more dangerous the road. Sometimes, one leg gets stuck in the snow, and if you accidentally step on it, it will fall into the valley.

Altitude is only a pure geographical term in the dictionary, but it has a special significance as important as life here. When we walk into Tibet, into the Himalayas, and into these deserted border defense barracks in the vast desert, we will deeply feel that high altitude is so awesome.

Tibetan border guards are constantly challenging the height of their lives in their posts. The higher the altitude, the higher the value of life and existence, and the higher the altitude, the higher the realm of thought and spirit. Those soldiers who forge heroic souls are the greatest lives standing on the roof of the world.
