The work is based on the image of the Toukoshan station and the continuous mountains and ridges as the background. In the picture, the helicopters are ready to go, appear and disappear unpredictably regardless of day or night and the weather. The special force brothers in arms transcend time, space and obstacles and bravely carry out the mission. They are not afraid of difficulties. They are a metaphor for the Tianlong Army in Toukoshan. They are the cornerstone and protective umbrella of national security and protection of freedom, democracy and the people.
