要在Midjourney中生成精准的文具产品场景图，必须用“角色标签+生活锚点”锁定用户身份：第一步开头明确【年龄+身份+典型行为】；第二步叠加强相关生活场景锚点；第三步删除所有模糊词，全部替换为具象视觉信号。

要在Midjourney中生成精准的文具产品场景图，必须让AI明确识别目标用户是谁，否则画面容易出现年龄错位、行为失真或环境违和——比如把高中生用的活页本放在老年大学讲台上，或让幼儿握着金属钢笔写字。
用“角色标签+生活锚点”锁定用户身份
第一步：在提示词开头直接写明核心用户群体，格式为【年龄+身份+典型行为】，例如“12-year-old middle school student → holding a pastel-colored mechanical pencil → flipping open a dotted A5 notebook”。
第二步：叠加一个不可替代的生活场景锚点，如“standing in front of a classroom whiteboard with handwritten math formulas”或“sitting at a wooden study desk with scattered sticky notes and a half-drunk bottle of bubble tea”。这个锚点必须和用户年龄/身份强相关，不能泛泛写“in a room”。
第三步：删掉所有模糊修饰词。把“young person”换成“9-year-old boy wearing light-up sneakers”，把“office worker”换成“30-year-old female graphic designer with blue-dyed undercut → typing on a MacBook with a washi-tape-decorated keyboard”。【Midjourney对抽象身份无感，只识别具象视觉信号】
避免用户混淆的三个高频错误
方法一：不单独写“student”或“teacher”，必须绑定标志性道具。写“high school teacher → wearing round glasses and holding a red pen → circling errors on a printed essay”比单写“teacher”有效十倍。
方法二：拒绝使用跨年龄段通用词。不要用“teenager”，改用“16-year-old high school junior → wearing oversized hoodie → sketching in a Moleskine sketchbook on a park bench”。【“teenager”在Midjourney中常被渲染成19岁模特脸，完全偏离中学生真实状态】
方法三：对儿童用户必须限定动作幅度和手部细节。“5-year-old girl → gripping a chunky triangular pencil → drawing wobbly sun with crayons on lined paper”中，“chunky triangular pencil”和“wobbly sun”是判断年龄的关键视觉证据。
不同用户群的提示词结构模板
小学生（6–12岁）：【age + grade + clothing detail】→ 【holding specific stationery type】→ 【doing physically constrained action】→ 【environment with learning cues】。例：“8-year-old third grader wearing cartoon-print backpack strap → gripping thick-barreled pencil with thumb-loop grip → tracing dotted letters on handwriting worksheet → at laminated classroom table with alphabet poster behind”。
大学生（18–24岁）：【age + major/role】→ 【using tech-adjacent stationery】→ 【in transitional space】。例：“22-year-old architecture student → sketching perspective lines with Rotring Isograph pen on trace paper overlay → sitting on beanbag in shared studio apartment with 3D printer humming nearby”。
职场新人（25–30岁）：【job title + industry】→ 【customized/organized stationery】→ 【micro-action showing habit】。例：“27-year-old UX researcher → flipping through bullet journal with color-coded tabs → underlining participant quote with fine-tip highlighter → at minimalist oak desk with dual monitors showing Figma wireframes”。
