This is their first-person diary. In a war so desperate that even the wind was cold, a group of children who have not grown up used their softest thoughts to give a little sweetness to those rushing to the front line. They don't know anything about strategic layout or industrial production capacity. They only know that stuffing an extra biscuit and drawing an extra sun can make those who drive Wugui fighters remember that there is still a temperature in the world worth turning back to in the smoke-filled sky.
Purpose: Use the "sweetness" in a child's eyes to counteract the cold cruelty of war - heroism on the front line is never a slogan, but a tacit and secretly conveyed small kindness: You leave me a piece of sweetness, and I will hide a little warmth for you. Even if you go to the battlefield without returning, some people will remember this soft warmth.
