The wind at the border carries the smell of poppies and also hides the footprints of countless anti-drug policemen.
Some people hide in the darkness and use their bodies as swords; some people rush to dangerous places and use their lives as a shield.
Their names are unknown, but their achievements live on forever.
Just for this mountain and river, it will never be covered in dust or extinguished.
Purpose: Taking the perseverance and sacrifice of the anti-drug police as the main line, showing their belief in using their lives to protect the lights of thousands of homes and safeguard the tranquility of their home and country, and pay tribute to all unsung heroes.
