When the scorching sun moved overhead of the "City of Sunshine", the tarmac of Lhasa Gonggar Airport was filled with heat waves. However, a group of people in white protective suits never stop shuttling between the tarmac and the cargo hold, opening the doors, unloading the cargo, loading, stacking, and closing the doors... The so called "Ant Team" - the stevedores repeat these works day after day.

At 5:00 in the morning, it was just dawn, and the mist around the mountains gradually dissipated. The infield stevedores in the sorting area had already started their work. Although the mechanization of Lhasa Gonggar Airport has been upgraded, baggage sorting still needs to be done manually. Luggage sorting is not only for ordinary checked luggage, but also for priority, large, and late luggage. Every day, the staff folds their waists and bends their legs, carefully placing pieces of luggage and goods.

"Large ones should not put on the small, and the heavy does not on the light." Luggage loading and unloading may seem simple, but it is a huge test of physical strength. During the COVID-19 epidemic, as key positions, their work has undergone great changes, not only do they wear ordinary protection equipment when working, but also should they wear protective equipment that matches the requirements for epidemic prevention and control. They are "fully armed", exposed to the scorching sun, their clothes completely soaked by the wanton flow of sweat, the hair on their foreheads wet, and the sweat dripped into the eyes along the hair tips. Wearing double gloves, their hands were already white and swollen after several hours of continuous handling. However, the staff never stop their work, putting each piece of goods in the designated position within the specified time.

At 2 a.m. the next day, the sky was dim and the stars were gradually disappearing. The stevedores, dressed in sweat-soaked clothes, walked out of the No. 5 crossing in twos and threes, dragging their tired pace.

In the loading and unloading support team, the oldest stevedore is 55 years old, and the youngest is just 19 years old. Most of them are the backbones of the family. In addition to the work in the airport, they have to join in spring plowing, summer weeding, autumn harvesting, and winter storing work of their family. In the ground service team, the more than 70 workers are all from the surrounding villages of Gonggar County. Now, they have become workers who have social security and receive wages every month. They are diligently working on their positions, realizing their life value.
