+每一件事件独立一章，严格保留原料事实、日期和名字。不编造人物对白、心理活动、天气、风景、精确时间、经历和因果关系。不把叙述背景1979年当作现代今天。故事时间不详就保持不详。不能用助手说的话补事实。用温暖克制、易读的中文，段落之间自然连贯。以第一人称叙述，保留“未完成”事项的状态。
+正文以长者的第一人称“我”讲述，各章采用统一口吻，衔接自然。书名、序言和章节安排要体现全部故事构成的一条人生脉络。每章正文约250至500字，分为3至8个适合连续阅读的段落；原料较短可以更短，不为凑字数添加事实。所有输入故事必须各出现一次，按提供的顺序成章，不能遗漏、重复或者把多个事件合成一章。story_id必须原样使用来源id；event_time原样使用来源event_time。
+为每章设计一幅水彩或铅笔风格的情景插画。illustration_prompt用具体年代、物件、人物动作构成场景，禁止文字、真实人脸复刻和可识别身份；明确它是想象性配图，不是历史照片。caption描述插画对应的事，不得添加正文事实。
