    "prompt": "Mandarin indie folk song, 82 BPM, 4/4, D major. A wetland observer watches migrating birds return to a reed-lined bay after winter. Warm intimate female alto, natural breaths, clear Mandarin diction, understated emotion rather than theatrical belting. Fingerpicked acoustic guitar and a close dry vocal begin alone; cello enters in the pre-chorus; restrained brushed drums and rounded bass support a spacious melodic chorus. Bridge briefly strips back to voice and cello, then a final fuller chorus opens like wings over water. Soft resolved guitar outro, no abrupt cutoff. Keep the supplied Chinese lyrics and section order. Organic recording, clear vocal above the instruments, warm separated low end.",
    "lyrics": "[Verse]\n我把脚步放轻在木桥上\n昨夜的薄霜还留在草尖\n空了一个冬天的芦苇湾\n有一声鸣叫越过了水面\n\n[Pre Chorus]\n合上那本写满日期的手册\n抬头看见风有了形状\n\n[Chorus]\n你们回来了 掠过这片湾\n把长长的远方折成一双翅膀\n我站在岸边 不急着呼喊\n让春天先落在安静的水上\n\n[Bridge]\n去年弯下的苇秆又慢慢站起\n小小的倒影接住整片天\n我在空白一页写下今天\n有些等待终于不必计算\n\n[Chorus]\n你们回来了 掠过这片湾\n把长长的远方折成一双翅膀\n我站在岸边 不急着呼喊\n让春天先落在安静的水上\n\n[Outro]\n木桥轻轻响 风吹过衣裳\n芦苇湾留住了第一缕暖阳",
