The ancient song "The Year of Peace" is the clue and spiritual core that runs through the entire text - the heroine's grandfather was once a palace musician, and fled with the remnants of music during the war. Before his death, he taught the female lead "The Year of Peace", telling her that "Peace is never something you wait for, it is achieved little by little by mortals who warm people with fireworks and protect their families with perseverance." The heroine will hum "The Year of Peace" every time she is in troubled times, which is a source of comfort. Borrowing yourself also inspires those around you; in the later period, the heroine and the hero lead the people to work, weave, and guard their homes. "The Year of Peace" becomes a tune for neighbors to gather, offer sacrifices, and pray for blessings. It ultimately echoes the core artistic conception of "peace in the world and the joy of the people", turning "Peace" from a prayer into a reality, fitting the essence of the ancient song "The Year of Peace" as "the simplest prayer for a peaceful life by people in troubled times."
